Daily RBRconcerto data from surface waters off of the Santa Monica Pier, California from April 16-25th, 2018 as part of the San Pedro Ocean Time-series (SPOT)

Abstract:

Daily casts with a RBRconcerto instrument were conducted at the Santa Monica Pier, California from April 16-25th, 2018 as part of the San Pedro Ocean Time-series (SPOT) project. Casts were conducted in surface waters (1-2 m depth) and measured conductivity, temperature, pressure, dissolved oxygen saturation, chlorophyll a, and salinity.

Methods & Sampling

Sampling and analytical procedures:
We used the RBRconcerto during the daily sampling period April 16-25th 2018 in surface waters off of the Santa Monica Pier, California. The RBRConcerto was lowered into the water for 10 minutes between 1 to 2 meters depth during which we sampled nearby sea water for downstream RNA extractions and 18S rRNA gene tag sequence processing.

Data Processing Description

RBRconcerto data was processed, trimmed and compiled with the OCE package in R (version 0.9-23). We trimmed the downcast and upcast parts of the data, resulting in consistent scans from 1000 to 2999 for each day.

BCO-DMO Data Manager Processing Notes (after communication with data submitter):

* added a conventional header with dataset name, PI name, version date
* modified parameter names to conform with BCO-DMO naming conventions
* blank values in this dataset are displayed as "nd" for "no data." nd is the default missing data identifier in the BCO-DMO system.
* added lat/lon values (in decimal degrees) to the dataset from the single deployment location provided in the metadata for this dataset.
* Added ISO_DateTime_UTC column from local time values
* pressure column rounded to two decimal places.
