Data Attributes

Attribute Summary

Name Type Description
100
CRUISE6 VARCHAR2 Code uniquely identifying cruise. The first four digits indicate the year and the last two digit uniquely identify the cruise within the year. The 5th byte signifies cruises other than groundfish: Shrimp survey = 7 (i.e. 201470), State of Massachusetts survey = 9 (i.e. 201491), Food habits = 5 (i.e.199554)
100
CRUISE VARCHAR2 Unique numerical code for a cruise.
100
STRATUM VARCHAR2 A predefined area where a net dredge, or other piece of gear was deployed. Code consists of 2 parts: Stratum group code number (2 bytes) and stratum number (3 bytes). Stratum group refers to if area fished is inshore or offshore North or South of Cape Hatteras or the type of cruise (shellfish, State of MA, offshore deepwater). The stratum number (third and fourth digits of code) refers to area defined by depth zone. See SVDBS.SVMSTRATA. The fifth digit of the code increases the length of the stratum number for revised strata after the Hague Line was established. Stratum group code: 01 = Trawl, offshore north of Hatteras; 02 = BIOM; 03 = Trawl, inshore north of Hatteras; 04 = Shrimp; 05 = Scotian shelf; 06 = Shellfish; 07 = Trawl, inshore south of Hatteras; 08 = Trawl, Offshore south of Hatteras; 09 = MA DMF; 99 = Offshore deepwater (outside the stratified area).
