Uptake of dissolved free amino acids, 15N uptake and Thymidine production</h3>
<p>
Prepared by U.S. JGOFS DMO for David Kirchman <br /></p>
<p>N biomass and N uptake by heterotrophic bacteria and phytoplankton were examined during the North Atlantic spring blooom (May 18-31, 1989) aboard the R/V Atlantis II in the vicinity of 47 N, 20 W. The ship followed drifting sediment trap arrays and samples were usually obtained in the morning from CTD/30 litre Niskin rosette casts.</p>
<p><b>DMO note:</b> <br />
These data lack sufficient metadata to accurately determine sampling location. Data were only reported from a total of 3 sampling locations, and although there were several CTD/Rosette casts done during each of those three days, it is possible through process of elimination to determine the correct station number by matching sampling depths in the bottle data object from this cruise. There are two possible matches for the data reported from 1989-05-20, so the position is estimated from both possible station locations as 46.8333N and 18.347W.</p>
<p> In hopes of making these data more useful, the DMO added metadata to this data object in September 2009, to support geolocation of the data.</p>
