Description

Intertidal samples collected during the spring, summer, and fall of 2011 along the coast of the Gulf of Maine at locations near Nahant, Massachusetts (42.4264 N, 70.9194 W; Boothbay, Maine (43.8920 N, 69.4773 W); and Lubec, Maine (44.8408 N, 67.0156 W). Data were collected at three sites in each of those three regions.

Methods & Sampling

Dataset acquisition description

Water samples were collected using acid-washed opaque bottles, filtered, and stored on ice for transport to the lab, where nitrate (NO3-, umol/L) and phosphate (PO4[3-], umol/L) were determined using a Lachat nutrient analysis system. Samples were taken from the intertidal zone, reaching into the surf. Samples were collected at each location (see lat and long for each measurement) on each date.

Data Processing Description

Dataset Processing Description

Data have not been processed. In the few instances were samples are missing (e.g., equipment error), those missing samples are indicated with 'nd'.

DMO Notes:

- original file: gom_coast_nutrients.csv
- added conventional header with dataset name, PI name, version date
- converted lat/lon to decimal degrees
- reformated date from d-mon-yy
- renamed parameters to BCO-DMO compatible names
- replaced spaces with underscores
- replaced missing data designated as a period with nd
