Description

This is a database/archive of nutrient and hydrographic data collected in the greater Gulf of Maine region. It is intended to be a 'nutrient' database, however temperature, salinity, and nitrate (reported as either NO3 or NO3+NO2) are included as variables, which may or may not include corresponding silicate or phosphate. Read more about these data from Rebuck et al. (2009).

Data include: month; day; year; decimal longitude; decimal latitude; bottom depth; sample depth; temperature; salinity; NO3+NO2; Si(OH)4; PO4; extracted chlorophyll; and quality flags.

Methods & Sampling

The nutrient data mining effort was led by D. Townsend (UMaine). After a careful calibration, those nutrient data were compiled into a database. The database includes more than 100,000 samples. The majority of data comes from two public sources: the World Ocean Database maintained at the National Oceanographic Data Center, and data assembled at the Marine Environmental Science Division at the Bedford Institute of Oceanography and the Marine Environmental Data Service in Ottawa, both a part of the Department of Fisheries and Oceans Canada. The two public sources were supplemented with additional data that have remained in provisional or unreleased status. More information is available on the project website and from Rebuck et al. (2009).
