Description

This dataset contains surface water cell counts of phytoplankton and of plastic pieces collected at the Carlsbad Desalination Plant, obtained in December 2014, Sept. 2015, May 2016 and November 2016.

Methods & Sampling

Samples were collected in a perimeter of ~1 km offshore of the discharge channel of Carlsbad Desalination Plant, Carlsbad Beach, California (33°08'18.9"N 117°20'21.3"W).

Samples were collected in four trips:
Pre-discharge: Dec 2nd-4th 2014 and Sep 21st-24th 2015.
Post-discharge: May 9th-12th 2016 and Nov 8th-11th 2016

Transect lines were deployed going from the discharge channel (Outflow) and the Intake to 1000 m offshore. Sampling was done every 25 m until 200 m offshore, then at 400, 600, 800 and 1000 m (“stations”). The "Parallel" transect ran continuous parallel to the beach ~200 m offshore and samples stations were deployed every ~100 m. Station 1 is the southern-most sampling point (south of discharge channel). At each station surface (~1 m depth) and bottom water samples were taken and a sediment sample. Bottom samples were collected at a depth range of 4m - 17m.

Unfiltered surface water samples were collected and preserved in formalin. Samples were set to settle over a minimum of 6 hours and species identified and counted by microscopy

Data Processing Description

BCO-DMO Processing:
- added conventional header with dataset name, PI name, version date
- modified parameter names to conform with BCO-DMO naming conventions: Fieldtrip to date_Fieldtrip; Individuals pr kg sediment to individ_kg_sed, Plastic pr. kg sediment to plastic_kg_sed
- added year column
- sorted by year
