CTD data in Santa Barbara Basin and Catalina Basin

Abstract:

CTD data (Conductivity, temperature, depth, Chl-a, and dissolved oxygen) at Catalina Basin (Latitude: 33.3005, Longitude: -118.6) and Santa Barbara Basin (Latitude: 34.22396, Longitude: -119.983) collected on on June 23rd, 2019 and June 27th, 2019, respectively on board R/V Oceanus using SeaBird SBE-911+. It showed the depth profile of different physiochemical properties of the water column at the Catalina Basin and Santa Barbara Basin sampling locations.

Methods & Sampling

The Conductivity-Temperature-Depth (CTD) instrument (SeaBird SBE-911+) equipped with the following sensors (Temperature, Conductivity, Pressure, Fluorometer, Dissolved Oxygen, Transmissometer, Photosynthetically Active Radiation (PAR) was initially tested and calibrated. The CTD rosette was mounted on a winch cable and underwent a brief "soak" at the surface for sensor equilibration. The CTD-rosette was then lowered into the water at a typical descent rate of ~ 0.5 meters per second, all the while logged data in real-time to the onboard computer. At ~1m above the sediment depths, the descent was paused. Then, the rosette-CTD system was ascended, and additional measurements were collected. The collected data was then post-processed to correct for sensor drift, followed by a thorough deployment documentation, including any anomalies or issues encountered.

Instruments

CTD Sea-Bird SBE 911plus

Supplied Name: CTD SeaBird SBE-911+

Supplied Description:

Instrument Type

Generic Name: CTD Sea-Bird SBE 911plus

Acronym: CTD SBE 911plus

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0058/

Generic Description:

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