The Ocean Archive System searches our original datasets as they were submitted to us, not individual points or profiles. If you want to search and retrieve ocean profiles in a common format, or objectively analyzed fields, your better option may be to use one of our project applications. See: Access Data

| Title: | Chlorophyll data associated with salp swarm collections in the Slope Waters off northeastern USA from R/V Oceanus OC370, OC379, OC381 in the slope waters off NJ, DE, MD from 2001-2002 (SalpSwarmDyn project) (NCEI Accession 0277369) |
| Abstract: | This dataset contains biological data collected on R/V Oceanus during cruises OC370, OC379, and OC381 from 2001-09-15 to 2002-09-25. These data include chlorophyll a, depth, and total phaeopigment. The instruments used to collect these data include Niskin bottle. These data were collected by Dr Patricia Kremer of University of Connecticut and Dr Laurence P. Madin of Woods Hole Oceanographic Institution as part of the "Salp Swarm Dynamics (SalpSwarmDyn)" project. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2023-01-23. The following is the text of the dataset description provided by BCO-DMO: chlorophyll data associated with salp swarm collections in the Slope Waters off northeastern USA Dataset Description: Chlorophyll data associated with salp swarm collections in the Slope Waters off northeastern USA.

| Supplementary information: | Acquisition Description: Seawater was collected with Niskin bottles at several depths and filtered through both GFF filters and 2 µm pore glass fibre filters for analysis of Chlorophyll a and total phaeopigment. Immediately after water samples were filtered, filter pads were transferred into 6 ml of 90% acetone and the pigment was extracted in a dark refrigerator for 24 hours. Filter pads were removed and the test tubes centrifuged just prior to reading the fluorescence. Following the initial fluorescence reading, samples were acidified with ~0.2ml of HCl and reread. The fluorometer was calibrated using a spectrophotometer during each cruise using standard Chl-a derived from spinach. Chlorophyll-a and phaeopigments were calculated from standard equations (Strickland and Parsons 1972). |
