Description

Methods & Sampling

Dataset acquisition description

Vessel CTD profiles were conducted from the outer reaches of the Damariscotta River Estuary in the mid-coast region of Maine from June 2017 to July 2018. Standard CTD profiling methods were used from the vessel.

Data Processing Description

Dataset Processing Description

Standard CTD data processing software from SeaBird.

BCO-DMO Processing Notes:
- 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)
- removed Type column, PI stated not applicable
- added column "station_name" to coincide with station ID numbers
- converted Dates supplied to YYYY-MM-DD format
- set Types for each data column

Niskin bottle

Supplied Name:

Supplied Description:

Instrument Type

Generic Name: Niskin bottle

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0412/

Generic Description:

A Niskin bottle (a next generation water sampler based on the Nansen bottle) is a cylindrical, non-metallic water collection device with stoppers at both ends. The bottles can be attached individually on a hydrowire or deployed in 12, 24, or 36 bottle Rosette systems mounted on a frame and combined with a CTD. Niskin bottles are used to collect discrete water samples for a range of measurements including pigments, nutrients, plankton, etc.

WET Labs {Sea-Bird WETLabs} C-Star transmissometer

Supplied Name:

Supplied Description:

Instrument Type

Generic Name: WET Labs {Sea-Bird WETLabs} C-Star transmissometer

Acronym: WL CSTAR Trans

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0160/

Generic Description:

The C-Star transmissometer has a novel monolithic housing with a highly intgrated opto-electronic design to provide a low cost, compact solution for underwater measurements of beam transmittance. The C-Star is capable of free space measurements or flow-through sampling when used with a pump and optical flow tubes. The sensor can be used in profiling, moored, or underway applications. Available with a 6000 m depth rating.
