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, 70.9194W; 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

Data were collected using shaded TidbiT dataloggers anchored to the rocky substratum in the mid-intertidal zone.

Data are average temperature readings in degrees C for each region and represent the average temperatures of the three sites in each region. The positions here are representative of the pooled sites for each region.

Data Processing Description

Dataset Processing Description

DMO Notes:

- original files: temp_water.csv temp_air_day.csv, temp_air_night.csv
- rearranged the temperature data so that the region and type of temperature reading are displayed as columns
- added lat, lon columns
- reformated date from m/d/yyyy to yyyy/mm/dd
- added conventional header with dataset name, PI name, version date
- renamed parameters to BCO-DMO compatible names
- replaced spaces with underscores
- reduced temperature significant digits to tenths of a degree
