Description

pCO2, pH, salinity & temperature collected off the coast of Oregon, USA, by a SAMI-CO2 or SAMI-pH. Salinity data was collected by a Seabird Microcat CTD - Shelf Break and NH10

Methods & Sampling

Dataset acquisition description

The NH10 SAMIs sampled on a 60 minute interval. The SAMI-CO2 ran a non-absorbing blank measurement every 3.5 days.

The Shelf Break SAMIs sampled on a 120 minute interval. The SAMI-CO2 ran a non-absorbing blank measurement every 3.5 days.

Instruments

CTD Sea-Bird MicroCAT 37

Supplied Name: Seabird Microcat CTD

Supplied Description:

Salinity data was collected by a Seabird Microcat CTD

Instrument Type

Generic Name: CTD Sea-Bird MicroCAT 37

Acronym: CTD MicroCAT 37

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/350/

Generic Description:

The Sea-Bird MicroCAT CTD unit is a high-accuracy conductivity and temperature recorder based on the Sea-Bird SBE 37 MicroCAT series of products. It can be configured with optional pressure sensor, internal batteries, memory, built-in Inductive Modem, integral Pump, and/or SBE-43 Integrated Dissolved Oxygen sensor. Constructed of titanium and other non-corroding materials for long life with minimal maintenance, the MicroCAT is designed for long duration on moorings.

In a typical mooring, a modem module housed in the buoy communicates with underwater instruments and is interfaced to a computer or data logger via serial port. The computer or data logger is programmed to poll each instrument on the mooring for its data, and send the data to a telemetry transmitter (satellite link, cell phone, RF modem, etc.). The MicroCAT saves data in memory for upload after recovery, providing a data backup if real-time telemetry is interrupted.

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).
