Description

SAMI-CO2, SAMI-pH, temperature and dissolved O2 data from Media Luna Reef, Puerto Rico

Media Luna Reef, NOAA CREWS buoy

Locations:
Reef Head: 17.9381N, 67.0403W, depth of 4m
Reef Tail (#2):17.9386N, 67.0519W, depth of 5m
Reef Tail (#3): 17.9353N, 67.0483W, depth of 4m

Methods & Sampling

Dataset acquisition description

The SAMIs sampled on a 30 minute interval. The SAMI-CO2 ran a non-absorbing blank measurement every 3.5 days. Oxygen was measured with a calibrated Aanderaa 4175 optode attached to a SAMI.

Instruments

Aanderaa Oxygen Optodes

Supplied Name: Aanderaa 4175 optode

Supplied Description:

Oxygen was measured with a calibrated Aanderaa 4175 optode attached to a SAMI.

Instrument Type

Generic Name: Aanderaa Oxygen Optodes

Acronym: AOO

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/351/

Generic Description:

Aanderaa Oxygen Optodes are instrument for monitoring oxygen in the environment. For instrument information see the Aanderaa Oxygen Optodes Product Brochure.

pCO2 Sensor

Supplied Name: SAMI-CO2 pCO2

Supplied Description:

SAMI-CO2 pCO₂ and Temperature mooring time series data collected on the Buzzards Bay mooring

Instrument Type

Generic Name: pCO2 Sensor

Generic Description:

A sensor that measures the partial pressure of CO2 in water (pCO2)

Submersible Autonomous Moored Instrument

Supplied Name: SAMI-CO2 pCO2

Supplied Description:

SAMI-CO2 pCO₂ and Temperature mooring time series data collected on the Buzzards Bay mooring

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).

Water Temperature Sensor

Supplied Name: SAMI-CO2 pCO2 and Temperature

Supplied Description:

SAMI-CO2 pCO₂ and Temperature mooring time series data collected on the Buzzards Bay mooring

Instrument Type

Generic Name: Water Temperature Sensor

Acronym: Water Temp Sensor

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/134/

Generic Description:

General term for an instrument that measures the temperature of the water with which it is in contact (thermometer).
