Notes on AR21 Leg 2 bottle data EXPOCODE 3175MB91_2 110309/dm 1. Original bottle data received from Bob Key as AR21a.leg2.Z on January 5, 2005. 2. AR21a.leg2.Z has no ALKALI data. TALK are in NOAA Data Report ERL AOML-24(dated April 1994) but are calculated data (uEq/Kg) and were not used. 3. DELC13 have no quality flags. Used flag 2. 4. CASTNOs do not match Summary file cast numbers from CTD data and NOAA Data Report ERL AOML-24(dated April 1994) Changed bottle data file cast numbers from all "1"s to Data Report cast numbers. 5. Bottom depths in AR21a.leg2.Z file differ from bottom depths in NOAA Data Report. Used Data Report values since they have better agreement with deepest bottle depths. For example, Station 4 deepest bottle is 5645m(5765db), Data Report bottom depth is 5908 and data file bottom depth is 3589m.
