Description

These are the processed CTD data from the DeZoZoo project taken from the mesohaline portion of Chesapeake Bay from 37.5 - 38.5 degrees N and from 76 - 76.5 degrees West.

Methods & Sampling

Dataset acquisition description

Data were collected using the shipboard SeaBird 9plus CTD fitted with a variety of sensors. Sensors are listed in the table below:

CTD was lowered to within 2 m of the bottom slowly, with bottom depth determined by CTD mounted altimeter. If samples were collected on a given CTD cast, they were collected as the CTD was raised back to the surface using the attached Rosette fitted with 10L Niskin Bottles.

Sensor	Serial Number
SBE 9plus pressure	0445
SBE Temperature 1	2574
SBE Temperature 2	2631
SBE Conductivity 1	2208
SBE Conductivity 2	2209
WetLabs FLNTU	091
SBE 43 Oxygen	0539
C-Star Transmissometer	n/a

Data Processing Description

Dataset Processing Description

Data were processed according to suggested post-processing routines outlined in the SeaBird Data Processing manual. Headers for the data processing routines are included in the .cnv files of post-processed data. All data were batch processed by cruise using the same routines and averaged in 0.5m bins.

Instruments

CTD Sea-Bird 911

Supplied Name: CTD

Supplied Description:

Standard CTD911+ with fluorometer and oxygen sensors working.

Instrument Type

Generic Name: CTD Sea-Bird 911

Acronym: CTD SBE 911

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0035/

Generic Description:

The Sea-Bird SBE 911 is a type of CTD instrument package. The SBE 911 includes the SBE 9 Underwater Unit and the SBE 11 Deck Unit (for real-time readout using conductive wire) for deployment from a vessel. The combination of the SBE 9 and SBE 11 is called a SBE 911. The SBE 9 uses Sea-Bird's standard modular temperature and conductivity sensors (SBE 3 and SBE 4). The SBE 9 CTD can be configured with auxiliary sensors to measure other parameters including dissolved oxygen, pH, turbidity, fluorescence, light (PAR), light transmission, etc.). More information from Sea-Bird Electronics.

Fluorometer

Supplied Description:

WET Labs ECO-AFL/FL

Instrument Type

Generic Name: Fluorometer

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/113/

Generic Description:

A fluorometer or fluorimeter is a device used to measure parameters of fluorescence: its intensity and wavelength distribution of emission spectrum after excitation by a certain spectrum of light. The instrument is designed to measure the amount of stimulated electromagnetic radiation produced by pulses of electromagnetic radiation emitted into a water sample or in situ.

Sea-Bird SBE 43 Dissolved Oxygen Sensor

Supplied Name: Oxygen sensor

Supplied Description:

SBE 43 Oxygen sensor

Instrument Type

Generic Name: Sea-Bird SBE 43 Dissolved Oxygen Sensor

Acronym: SBE-43 DO

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0036/

Generic Description:

The Sea-Bird SBE 43 dissolved oxygen sensor is a redesign of the Clark polarographic membrane type of dissolved oxygen sensors. more information from Sea-Bird Electronics
