     1.1 SUMMARY AND ITINERARY 
         (G. Kattner)
     
     The main objectives of the research program were in the field of 
     physical and chemical investigations. Continuous underway measurements 
     in air and surface water have been completed by station work where water 
     sampling was performed down to the bottom. In the equatorial region and 
     along the route to the Argentine Basin floats were launched which will 
     drift in a depth of about 800 m. They will collect data on position, 
     pressure and temperature. These studies are part of WOCE, a program to 
     obtain the most comprehensive description and understanding of the 
     circulation of the world oceans. The chemical investigations focused on 
     trace substances of biogenic and anthropogenic origin. The measurements 
     of dissolved organic substances will expand and generalize the present 
     knowledge on larger scales. The same holds true for the determination of 
     halogenated hydrocarbons as well as N20, which were analyzed in water 
     and air. Especially the contribution of the ocean to atmospheric 
     methylbromide has been investigated. During the whole cruise trace 
     metals were determined in surface water and air. Additional rain samples 
     have been taken in the ITCZ to follow the atmospheric heavy metal flux 
     to the Atlantic Ocean.
     
     Samples to measure atmospheric mercury over the Atlantic Ocean have been 
     taken. These measurements continue studies some years ago to obtain data 
     for estimations of global trends. Hydrogen peroxide, formaldehyde, 
     carbon monoxide and ozone were determined to provide further information 
     about the chemistry of the atmosphere since these compounds are involved 
     in many chemical atmospheric reactions. The distribution of aerosol 
     particles was measured and will provide new information about 
     nucleation, size and concentration of particles. A considerable number 
     of investigations are connected to long-term research programs, which 
     will contribute to the knowledge of global scale processes and trends. 
     The cruise track is given in Fig. 1.
     
     At 10 o'clock on October 18th, 1994, the ANT X11/1 cruise started out of 
     Bremerhaven. After passing the lock and leaving the Weser delta with 
     course to the English Channel, onboard measurements already started. 
     After a smooth beginning of the cruise during the first two days, we got 
     caught in some heavy weather on October 20th south of Dover. RV 
     "Polarstern" steamed and rolled through 8-10 m high waves and working 
     got a little tiresome. Around noon of the 23rd we crisscrossed a certain 
     area three times to test the Hydrosweep-Sidescan- System, that records 
     bottom structures. All significant structures of a particular seamount 
     could be found. Following that, the first CTD was deployed and water 
     samples were taken. On October 24th thirteen cruise participants left 
     the ship on the evening of that day on a little pilot boat to Punta 
     Delgada on the Azores.
     
     Since October 25th, the cruise continued in calm seas and rapidly got us 
     close to the equator. The continuous measurements of all air and water 
     scientists proceeded as planned and delivered large amounts of data. The 
     cruise proceeded along 28°W longitude due south. We passed the Cape 
     Verde Islands and only short interruptions were caused by the CTD and 
     sampling from the bow crane, On the morning of the 30th, another short 
     CTD was carried out and afterwards we started chasing rain. A lot of 
     rain samples were collected along with simultaneously taken seawater 
     samples. These samples will be analyzed later for trace metals in order 
     to determine the input from rain into the surface water. On the 
     afternoon of the 31st, during the equator ceremony 25 crew members and 
     scientists were thoroughly cleansed.
     
     On November 1st, we reached the position for the first float launching 
     at 20° north. From now on, about 120 deployments of floats and surface 
     drifters were performed on our way south. On November 9th, we were 
     roughly at the latitude of Rio de Janeiro. On November 15th, a sound 
     source was brought out to complete the web of sound sources that were 
     deployed in the southwest Atlantic. On the 20th of November, we reached 
     the Strait of Magellan and after another 100 nautical miles to go we 
     reached Punta Arenas in the early morning of the 21st. The cruise had 
     covered a total of 8600 nautical miles from Bremerhaven to Punta Arenas.
     
     
     1.2   METEOROLOGY
     
     1.2.1 WEATHER CONDITIONS 
           (Klaus Dittmer and H. Köhler)
     
     At the beginning of the cruise the synoptic situation was dominated by a 
     high over eastern Europe and a low with winds of gale force near 
     Ireland. Easterly winds increased to 7, for a short time 8 Bft, between 
     these to pressure systems in the North Sea and English Channel. However, 
     the sea and swell remained relatively low due to short fetch.
     
     From October 19th to 22nd a large-scale depression moved from the West 
     Atlantic to England, taking a relative southern track. Minimum pressure 
     in the centre of the low was about 973 hPa. In the region of the trough 
     of this system westerly winds up to 10 Bft were measured in the early 
     morning of October 22nd. Windsea and swell could develop to mature 
     stage, in this case 8 to 10 m, associated with isolated freak waves of 
     11 to 13 m. The synoptic development as well as the sea state were 
     calculated very accurately by the numerical models of the German weather 
     service, thus a warning could be issued on time.
     
     West of 15°W wind and sea decreased rapidly. Approaching the Azores a 
     flat low with intermittent rain was passed, but some miles northeast of 
     Sao Miguel, the clouds broke up at sea and only the mountains of the 
     island were still covered by cumulonimbus. On the route to the tropics 
     the airmass was still unstable in a northerly flow and showers occurred 
     at times. The Intertropical Convergence (ITC) was reached near 7°N on 
     October 30th. At this time it was poorly developed. Just in the direct 
     convergence of northeasterly and southeasterly winds a line of isolated 
     showers could be observed. For 24 hours it was intended to get as much 
     samples of rain as possible; therefore showers were detected by Radar. 
     During the measuring campaign the convective belt intensified slowly. 
     The water surface temperatures were 29 to 30°C in the ITC, which is 
     about 2 degrees above the normal climatological values for this time.
     
     In the South Atlantic RV "Polarstern" first sailed at the edge of the 
     subtropic anticyclone. Southeasterly winds from 4 to 6 Bfi and a 
     southerly swell of about 3 m were encountered. The swell was caused by a 
     storm west of the subtropical high. The storm depression developed off 
     the coast of North-Argentina and drifted eastward very slowly. Thus, the 
     sea reached its possible maximum height due to long fetch and duration 
     of high wind speeds. Until about 20°S the vertical formation of layers 
     was unstable up to 2 km height. The cloud base was near 500 m. 
     Nevertheless isolated short showers developed. The cold front of a storm 
     depression near South Georgia became stationary along 25°S and began to 
     clear when we arrived in this area.
     
     On November 9th a wave depression had built up over the River Plate 
     mouth. It developed to an intensive low of 995 hPa and moved eastwards 
     very slowly. Thus, we remained on the front side for a longer time and 
     the maximum winds from north encountered were 7 Bft. In the rear of the 
     weakening low westerly winds of about 5 Bft affected the vessel. On 
     November 13th and 14th RV "Polarstern" sailed in the area of a high 
     pressure system with light and moderate winds.
     
     The coldfront of a low between the South Orkney and South Shetland 
     Islands became stationary for a time east of Bahia Blanca on October 
     15th and waves developed along the front. Crossing the front winds 
     increased up to 7 Bft in showers. During the night from October 15th to 
     16th the front moved backwards and fog patches occurred in light warm 
     northerly winds. On October 16th a new wave along the front developed to 
     a complex low of less than 990 hPa in a rather unexpected manner. It 
     moved eastward just south of our position. For a short time maximum 
     winds were 10 Bft in the rear of the center. On October 17th a high 
     pressure system built up over northern Argentina and strong, later 
     moderate cold southwesterly winds affected RV "Polarstern".
     
     To the end of this leg a secondary depression belonging to the typical 
     large scale low over the Bellingshausen Sea developed west of the Strait 
     of Magellan. It crossed southern Patagonia during the night from of 
     November 19th to 20th. Strong northerly winds occurred in front of this 
     system, strong westerly winds in the rear. With the passage of the 
     frontal trough wind speeds of Bft 8 were measured. Due to short duration 
     of the gale no significant sea could develop. 
     

     1.3   Physical OCEANOGRAPHY
     
     1.3.1 RAFOS FLOATS IN THE SOUTH ATLANTIC 
           (0. Boebel, M. Menzel, C. Schmidt and A. Pinck)
     
     A contribution to the understanding of the deep circulation is one of 
     the goals of the IfM Kiel 'RAFOS float' project. In the South Atlantic, 
     the advection of the Antarctic Intermediate Water (AAIW) shall be 
     explored. This water mass is found beneath the South Atlantic Central 
     Water at latitude dependent core depths ranging from 700 to 900 m. It 
     may be distinguished from the water above and the North Atlantic Deep 
     Water below, by its distinctive salinity minimum and oxygen maximum. The 
     AAIW may be observed in the subtropical and tropical regions of the 
     South Atlantic. The site of formation is supposedly close to the 
     Subpolar Front.
     
     RAFOS-FLOATS
     
     RAFOS floats are well suited to explore this water mass. These drifters 
     float freely at a predetermined depth. They house a microcomputer, which 
     determined the float's position by acoustic tracking and measures 
     pressure (p) and temperature (T) once a day. The acoustic tracking is 
     achieved by measuring time of arrivals JOA) of coded sound signals 
     transmitted by moored sound sources. The data quintuplet (p,T,3xTOA) is 
     stored and subsequently transmitted to Kiel by ARGOS satellite system, 
     once the float has returned to the sea surface after finishing its 
     underwater mission, which may last for up to two years.
     
     The POLARSTERN cruise ANT X11/1 was the last of three float seedings 
     performed in the area by IfM Kiel. During the previous expeditions 
     METEOR 22 (M22) and METEOR 28 (M28) 23 and 29 floats were seeded, 
     respectively. During the ANT XII/1 cruise a total of 42 RAFOS floats 
     were deployed, one at every degree of latitude, covering the western 
     South Atlantic from the equator to 39°S. The floats were programmed to 
     mission lengths ranging from 361 days (1 year) to 721 days (2 years), as 
     shown in more detail in Tab. 1. This results in a total of 52 float 
     years or an average under water mission length of 14.8 month per float.

     The floats were ballasted to reach neutral buoyancy at the depth of the 
     salinity minimum of the AAIW. This depth was determined using CTD-casts 
     taken (in most cases) just before float launch. Trajectories obtained so 
     far from 15 floats (Fig. 1.3.1 - 1) launched during M22 show a mean flow 
     of 5 cm/s in dominantly western directions between 25°S and 32°S. The 
     ALACE (see below) data provided by R. Davis, however, depicts a strong 
     eastward flow at 40°S. Thus, for a working hypothesis, the assumption of 
     the center of a recirculation cell of AAIW at 36°S is reasonable, and 
     was used for the determination of the sound source position and float 
     deployment pattern.
     
     CTD & ROSETTE
     
     A total of 43 CTD casts were taken during ANT XII/1. The CTD was used 
     with a 24 bottle (10 L each) rosette to draw water samples. At seven 
     stations, deep casts were taken to at least 3000m, in order to provide 
     the organic and anorganic chemists on board with water from different 
     water masses. In particular, water was taken from the Mediterranean 
     Outflow Water, the upper, middle and lower North Atlantic Deep Water, 
     the Antarctic Intermediate Water and the Antarctic Bottom Water. The 
     majority of the casts however, were terminated at 1500 m, covering the 
     AAIW layer to determine the depth of the salinity minimum. 
     
     Originally, the CTD-data, using an ICTD from FSI, was noisy, especially 
     with respect to pressure spikes. During profile #10, the CTD finally 
     broke down, due to the failure of a DC/DC converter, as determined 
     later. While repairing the broken unit, the opportunity was used to 
     change the release unit of the rosette from a non-interrupting type 
     (EG&G) to an interrupting type (GO). This change resulted in a much 
     better data quality, starting with station #11. However, a mismatch of 
     the time constants of the conductivity and the temperature sensor 
     results in false on line salinity data especially in layers of high 
     temperature gradient. Thus, the raw data distributed to various groups 
     aboard the ship should be used for qualitative statements only. A 
     revised data set, using the data of the CTD-bound fast temperature 
     sensor to calculate salinity, will be available later.
     
     The accuracy of the CTD-data was controlled by use of reversing 
     thermometers and water samples of the bottles taken, analyzed using an 
     Autosal 2000. The bias observed by reversing thermometers as compared to 
     the CTD data are less than 0.002 C. The salinity data indicated that the 
     raw data shall be corrected by +0.018 psu to a slightly higher (real) 
     salinity. 
     
     Fig. 1.3.1-2 shows the salinity and temperature section obtained from 
     the raw data. One can clearly observe the salinity minimum of the AAIW 
     ranging from 40°S to 20°S. The AAIW tongue ceases at 20°N, where it 
     faces high salinity water from the north. At 40°S the northern border of 
     the probable formation area of AAIW is indicated by an outcrop of the 
     isohalines and isotherms. Here, the lowest salinities during the whole 
     cruise were observed. The salinity minimum of the AAIW rises slowly from 
     approximately 950 dbar at 40°S to 700 dbar at 10°N. The overlying 
     thermocline water reached a temperature and salinity maximum slightly 
     north of the equator at 5°N. 
     
     SOUND SOURCES
     
     During M22, four sound sources were deployed around the Rio Grande Rise 
     in addition to an American sound source array deployed farther north. 
     During M28 two sound sources were added by IfM Kiel. The sound source K6 
     deployed during POLARSTERN cruise ANT XII/1 in the western Argentine 
     Basin at 40°03.14'S, 50°08.54'W extends the area covered by sound 
     signals to the south in order to track floats as far as 40°S. The sound 
     source was programmed to beep at 00:30 GMT and is approximately 1.5 s 
     late.
     
     In preparation of the mooring, the release unit was tested, lowering it 
     to 2000m. An attempt to acoustically communicate with the unit by use of 
     a passive hydrophone failed at this depth, much like a second attempt at 
     1000 m. However, one of the 4Release4 commands given at 2000 m and 1000 
     m release unit depth resulted in the release of a chain attached to the 
     release unit.
     
     ALACEs and MARVORs
     
     In addition to the Kiel RAFOS floats, eight ALACE floats (Autonomous 
     Lagrangian Current Explorer) were launched to cover the region south of 
     the sound source array, particularly the Falkland Current. These 
     instruments operate independent of sound coverage and were kindly 
     provided by Ray Peterson (Scripps Institution of Oceanography). Every 
     fortnight, they return from their 800 m or 1000 m drifting depth to the 
     sea surface for a few days and are positioned using the ARGOS system. 
     The resulting data gives a coarse picture of the deep circulation. 
     
     Further, 29 MARVOR floats seeded during this cruise by Michel 
     Ollitrault, IFREME Brest, will broaden the emerging picture concerning 
     diffusivity and advection.
     
     
     SURFACE DRIFTERS
     
     In addition to subsurface drifters the motion of the upper layer is 
     observed by the use of surface drifters drogued at 100 m. These drifters 
     were provided by W. Kraus IfM Kiel, and shall monitor the motion of the 
     thermocline water. During previous expeditions a total of 150 drifters 
     were deployed in the South Atlantic. During the cruise 35 drifters were 
     seeded between 2°S and 46°S at positions uncovered so far by 
     trajectories.

                     oriented solid line represents the wake of M28 (May 1994), 
                     crosses indicating launch positions of floats. The north-
                     south oriented sequence of crosses mark the launch 
                     positions of floats and drifters during ANT XII/I.

     05/10/00  Krause      CTD        Data are Public
               I have been in correspondence with Bert Thompson 
               concerning the above data. They are available, and I have 
               agreed to include them on the disc for public use. My co-
               worker Dr. Gereon Budeus (mailto:gbudeus@awi-
               bremerhaven.de) has the data set on his computer ready 
               for immediate transfer. Apparently he does not have the 
               right adress for the transfer. Please, arrange with him a 
               suitable procedure.

     06/23/00  Budeus      CTD        Submitted
               Today I transferred the data files of the Polarstern 
                cruise ANTXII via ftp to the INCOMING directory.
                • The files are ascii, but not in WOCE format.
                • The names are as follows:
                  an12xxxy.c00
               with an12 for the cruise, xxx for the station, and y for 
                 the cast starting with 0 for the first. It is only 
                 downcasts. The columns are  p/dbar, t0(68)/deg C, 
                 theta0(68)/deg C, s00, sig-t00, sig2-th00 with the 0 
                 indicating the primary sensor set.
               The positions are listed in the header.
               The data can be public. The PI who has collected the data 
                 is Jueri Sildam who was working then at AWI; ship is RV 
                 Polarstern.
               If there are any further questions or needs, or if the 
                 format should be different, please give me a note.

               Expocode changed from "_4" to "_1" & cruise dates changed
               DAC dates: 10/18/94-11/22/94, expo 06AQANTXII_1 
                 Polarstern was in Pacific in March 95! The 94 cruise 
                 contact is Olaf Boebel who is now at URI. 43 CTD and 
                 bottle stations were done as well as a lot of float 
                 deployments

     04/10/01  Schmid      DOC        Entire doc already submitted
               I have only one copy of the report. p. 6-11 are all there 
               is with respect to the WOCE data we submitted. The 
               complete report was published by AWI, Bremerhaven, 
               Germany. You can try your luck with Olaf Boebel (he and I 
               were on leg one of the cruise together with a lot of 
               scientists from AWI and other institutions). Olaf is now 
               at AWI. His email address is <oboebel@awi-bremerhaven.de

     12/14/01  Bartolacci  CTD        Website Updated Data OnLine
               Reformatting Needed:
                 I have created a directory for this cruise, and placed 
                 the CTD files sent by G. Budeus on line. These files are 
                 not in woce format at this time and need significant 
                 reformatting. Correspondence will be initiated with 
                 Budeus regarding obtaining data in woce format. No other 
                 data has been submitted at this time, data are public.

     12/17/01  Bartolacci  CTD        Update Needed; Data need reformatting
               I am writing to inquire about the Polarstern CTD data 
                 submitted back in June of 2000.  My apologies for only 
                 now contacting you, but our queue of data problems and 
                 inquiries is quite large.
               I am in need of some clarification and information 
                 regarding the data and am hoping you can help.
               My first question is to inquire if these data are 
                 available in WOCE format.  The list of data in need of 
                 reformatting by the WHP Office is quite large.  Obtaining 
                 data in WOCE format will speed up the process of getting 
                 these data online and relieve some of the massive 
                 reformatting burden.  If not, these data will be 
                 reformatted by the Office in due time.

     12/17/01  Bartolacci  CTD        Data need reformatting  (continued)
               In order to reformat these data we need some information 
                 missing from some of the station files, or a resubmission 
                 of these station files. The email pertaining to the data 
                 submission indicated that the station positions are 
                 located in the header information.  However, the first 16 
                 stations (an120010.c00 through an120142.c00) are missing 
                 the top 14 lines of header information.  These lines 
                 would contain the crucial header information, including 
                 station latitude and longitude, necessary to create WOCE 
                 formatted CTD and summary files.  Is it possible to get 
                 this header information for the above mentioned stations, 
                 or perhaps get the stations resubmitted to ensure all the 
                 data are included?
               Also, we'd like to confirm that no bottle data are 
                 associated with this cruise, and that no station summary 
                 file exists at this time, however if there is a file 
                 containing the station summary information, may we obtain 
                 it from you as well?
               Any information you can provide about this data will be 
                 greatly appreciated.  Thank you for your consideration 
                 and cooperation. If you should have any questions 
                 regarding this email or any WOCE hydrographic data, 
                 please do not hesitate to contact me.

     05/01/02  Bartolacci  CTD        Data need reformatting. 
               Database incorrect. No SUM or DOC either.  Data PI Budeus 
               has been emailed regarding problems and missing files. 
               Fix database for parameters.

     05/14/02  Bartolacci  SUM        Website Updated; Data Reformatted/OnLine
               I have reformatted the SUM file extracted from paper text 
                 copy submitted to JKappa. Newly reformatted SUM file 
                 passes WOCE format checks with no errors. However there 
                 is a mismatch between the CTD files submitted by Budeus 
                 in 6/00 and the recently reformatted sumfile. Station 
                 numbers, lat/lon and dates do not match between files. 
                 Doc file indicates that a second leg of this cruise took 
                 place in 1995 (dates within CTD files), so perhaps the 
                 CTD data are from leg 2 and summary file we currently have 
                 covers leg 1. Budeus will need to be contacted again to 
                 clarify.
               SUM:
                 • extracted file was from text and comma separated.
                 • data was converted to column format, headers were 
                   corrected where needed
                 • all columns were aligned to WOCE format.
                 • changed expocode from 06AQANTXII/1 to 06AQANTXII_1
                 • added place holding zero to lat/lon where needed. 
                 • corrected year for 3 dates (changed 49 to 94)
               NOTE:  It appears that the CTD station files and the 
                      summary file are for two different legs of this 
                      cruise, however presently we only have information 
                      and documentation for leg 1.  CTD station files 
                      may be for leg 2 (1995 whereas leg 1 is 1994)
               UNC DEPTH for station 33-122 in SUM file appears to be 
                 incorrect (all other stations are deep i.e. 33-121 depth 
                 is 4842, 33-123 depth is 4344, however 33-122 depth is 
                 455). However when attempting to compare the CTD station 
                 file for this cruise with the summary file information, 
                 it was noted that CTD station files submitted by Budeus 
                 in 2000 do not match in station number, lat/lon or date.
               PI should be contacted again regarding the differences in 
                 these two files.
