Methods & Sampling

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

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.
