MOCNESS-1 Plankton Abundances from the R/V Wecoma, R/V New Horizon W0004B, NH0005, W0007A, NH0007, W0009A, W0204A, W0205A from the Northeast Pacific, 2000 and 2002 (NEP project) (NCEI Accession 0277260)

This dataset contains biological, physical, and survey - biological data collected on R/V New Horizon and R/V Wecoma during cruises NH0005, NH0007, W0004B, W0007A, W0009A, W0204A, and W0205A in the North Pacific Ocean from 2000-04-11 to 2002-05-30. These data include abundance, depth_bottom, stage, taxon, and taxon_code. The instruments used to collect these data include MOCNESS1. These data were collected by Dr William T. Peterson of Northwest Fisheries Science Center - Newport as part of the "U.S. GLOBEC Northeast Pacific (NEP)" project and "U.S. GLOBal ocean ECosystems dynamics (U.S. GLOBEC)" program. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2023-01-23.

Data Description

The MOC1 data are organized by cruise within year. The master page (Level 0) lists all of the cruises in chronological order. Clicking on a cruise will show all of the casts collected/processes from that cruise (Level 1). Clicking on a cast will bring up the Level 2 file that shows all of the samples (nets) processed from that cast. Clicking on the sample_id (ranges from "1" to "8" for this type of data) will display the Level 3 data, which are the actual taxonomic categories and abundances for that particular sample. Additional info about the variables is described below.

Program Codes Description
LTOP samples collected on Long-term Observation Program Cruises (ca. 4-6 cruises per year; all sample the Newport Hydrographic (NH) Line; some sample other standard lines further south)
MESO_1 samples collected from process cruise in June 2000
MESO_2 samples collected from process cruise in August 2000
MESO_3 samples collected from process cruise in June 2002

Life Stage Info Codes
(partial listing) Description
most are self-explanatory; Male, Female, CV ==> Copepodite 5, Zoea, Nauplii, N2 => Nauplius 2, Egg--a few are not, esp. for the euphausiids (Thysanoessa and Euphausia)
F2 Second Stage Furcilia (aka Furcilia 2)
F3 Third Stage Furcilia (aka Furcilia 3)
F1_0 First Stage Furcilia with 0 legs
F2_32 or Furcilia_2_3L2S Second Stage Furcilia with 3 pairs of legs total, with 2 pairs of legs having setae; this xLyS pattern is common, with x and y varying depending on stage of development

MOCNESS Sample Analysis Protocols from "comments" field
Comment Description
Proc_Protocol=0 (Standard Protocol): 1) Count, sex, measure, and stage all euphausiid species. 2) Count and measure Limacina pteropods 3) Count, stage, and measure both spp. of Neocalanus 4) Count and measure "Big Stuff" (large zooplankton, i.e., fish larvae, squid, octopi, jellies, other shrimp, etc...)
Proc_Protocol=1 (Euphausiids only Protocol): 1) Count, sex, measure, and stage all euphausiids.
Proc_Protocol=2 ('Acoustic Calibrations' Protocol): 1) Count, sex, and measure all euphausiids (Adults and juveniles ONLY). 2) Count and measure Limacina pteropods.
