abstract: Two sets of CTD data were taken during the 2010 surveys of the Louisiana continental shelf. Hydrographic data were obtained with the LUMCON SeaBird 911+ CTD system and a YSI 6820. Nutrient, pigment, suspended sediment, surface salinity, Secchi depth, and station information data were also acquired.
purpose: The physical, biological and chemical data collected are part of a long-term coastal Louisiana dataset. The goal is to understand physical and biological processes that contribute to the causes of hypoxia and use the data to support environmental models for use by resource managers.
credit: Funding for data collection and processing was provided by the National Oceanic and Atmospheric Administration, Center for Sponsored Coastal Ocean Research, Grant No. NA09NOS4780204 to Louisiana Universities Marine Consortium.

code: Secchi disk
type: Secchi disk
description: The Secchi disk (or Secchi disc), as created in 1865 by Angelo Secchi, is a plain white, circular disk 30 cm (12 in) in diameter used to measure water transparency or turbidity in bodies of water. The disc is mounted on a pole or line, and lowered slowly down in the water. The depth at which the disk is no longer visible is taken as a measure of the transparency of the water. This measure is known as the Secchi depth and is related to water turbidity. [Wikipedia, 2021-09-02]
