Description

Vessel CTD profiles in the outer reaches of the Damariscotta River Estuary on the mid-coast region of Maine from June 2017 to July 2018.

Acquisition Description

Standard CTD profiling methods used from the vessel.

Processing Description

Standard CTD data processing software from SeaBird.

BCO-DMO Data Manager 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 all spaces in headers and replaced with underscores
* removed all units from headers
* removed Type column, PI stated not applicable
* removed YSI data tab, PI not serving
* restructured excel sheet to eliminate "Station Key"
* added column "station_name" to coincide with station id's.
* converted Dates supplied to ISO Date format
* set Types for each data column

LI-COR Biospherical PAR Sensor

(more info)

Short Name: LI-COR Biospherical PAR

Community Standard Description

Generic Description

The LI-COR Biospherical PAR Sensor is used to measure Photosynthetically Available Radiation (PAR) in the water column. This instrument designation is used when specific make and model are not known.

PI supplied instrument name: Biospherical scalar PAR sensor

Dataset-specific description

Niskin bottle

(more info)

Short Name: Niskin bottle

Community Standard Description

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 CSTAR Transmissometer

(more info)

Short Name: WL CSTAR Trans

Community Standard Description

Generic Description

A highly integrated opto-electronic design to provide a low cost, compact solution for underwater measurements of beam transmittance. The instrument is capable of either free space measurements, or through the use of an optical flow tube, flow-through sampling with a pump. It can be used in profiling, moored, or underway applications. more information from Wet Labs
