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
