The counts of each euphausiid species for each net were standardized to the number of individuals\/1000m3 for each depth stratum using the volume filtered by each net. The cumulative percent abundance (Baker, 1970; Pennak, 1943) was calculated starting from the bottom of each tow (i.e., the bottom of the first depth stratum where a species occurred was assigned 0 percent and the top of the final depth stratum of occurrence was assigned 100%). Depth (m) values of 25%, 50%, and 75% occurrence were interpolated based on the cumulative curve.<\/p>\n
BCO-DMO Processing:<\/strong><\/p>\n- added conventional header with dataset name, PI name, version date
\n- renamed parameters to BCO-DMO standard
\n- replaced space with underscore
\n- replaced blank cells with nd
\n- added activity, ISO_DateTime_Local columns
\n- changed cast type from MOC1 to MOC.25<\/p>\n
2016-04-22: to enable joining: krill_by_sp and krill_by_tow: Changed instrument (was called cast_type)\u00a0from MOC.25 to MOC-25 and changed tow from m_25_00# to #.<\/p>\n
2016-05-04:\u00a0created a new dataset by joining 'MOCNESS tow metadata' and earlier version of 'Krill abundance by tow', then manually added hypertext links to the appropriate tow physical data from 'MOC_CTD_RedSea'.<\/p>\n
version 3. 2022-05-26:
