This version of this dataset is considered deprecated/obsolete. Please use the new dataset at: https://www.bco-dmo.org/dataset/826798

Methods & Sampling

Data are collected from a Sunburst SAMI-pH deployed at a floating dock at ~2-3 m water depth located at the University of Washington Friday Harbor Laboratories, Friday Harbor, WA (Lat = 48.5461, Long = -123.007). This dataset contains values of pH and water temperature.

Data Processing Description

BCO-DMO Processing:
- concatenated separate data files (.txt) into one;
- added ISO 8601 date/time format;
- added latitude and longitude as columns; values originally provided in dataset metadata.

Instruments

Submersible Autonomous Moored Instrument

Supplied Name: Sunburst SAMI-pH

Supplied Description:

Sunburst SAMI-pH (pH and temperature)

Instrument Type

Generic Name: Submersible Autonomous Moored Instrument

Acronym: SAMI

Generic Description:

The Submersible Autonomous Moored Instrument (SAMI) measures and logs levels of dissolved chemicals in sea and fresh water. It is a plastic cylinder about 6 inches wide and 2 feet long that is self-powered and capable of hourly measurements for up to one year. All data collected are logged to an internal memory chip to be downloaded later. SAMI sensors usually are placed a few feet underwater on permanent moorings, while others on floating drifters sample the water wherever the wind and currents carry them. The instruments have been used by researchers around the globe in a variety of studies since 1999. Dr. Mike DeGrandpre, University of Montana, developed the SAMI between 1990 and 1993 during his postdoctoral work at the Woods Hole Oceanographic Institution (Woods Hole, MA, USA).
