Time-Series of Phytoplankton Taxonomy and Density collected by the CARIACO Ocean Time-Series Project from November 1995 to January 2017 (NCEI Accession 0277383)

This dataset contains biological and survey - biological data collected on B/O Hermano Gines during cruise HG93_CARIACO from 1995-11-08 to 2017-01-12. These data include abundance, species, and taxon_code. The instruments used to collect these data include Microscope-Optical and Niskin bottle. These data were collected by Ramon Varela and Yrene Astor of Estacion de Investigaciones Marinas de Margarita, Luis Troccoli, Rafael Diaz-Ramos, and Sonia Subero-Pino of Universidad de Oriente, Venezuela, and Dr Frank Muller-Karger of University of South Florida as part of the "CARIACO Ocean Time-Series Program (CARIACO)" project and "Ocean Carbon and Biogeochemistry (OCB)", "Ocean Time-series Sites (Ocean Time-series)", and "U.S. Joint Global Ocean Flux Study (U.S. JGOFS)" programs. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2023-01-23.

CARIACO time series Phytoplankton taxonomy from samples collected during CTD/Niskin casts

Dataset Description:
The CARIACO Ocean Time-Series Program (formerly known as CArbon Retention In A Colored Ocean) started on November 1995 (CAR-001) and ended on January 2017 (CAR-232). Monthly cruises were conducted to the CARIACO station (10.50° N, 64.67° W) onboard the R/V Hermano Ginés of the Fundación La Salle de Ciencias Naturales de Venezuela. The program studied the relationship between surface primary production, physical forcing variables like the wind, and the settling flux of particulate carbon in the Cariaco Basin. This depression, located on the continental shelf of Venezuela, shows marked seasonal and interannual variation in hydrographic properties and primary production (carbon fixation rates by photosynthesis of planktonic algae).

One of the monthly measurements taken by the program was water sampling at different depths for phytoplankton taxonomy (occurrence and density). Those water samples were collected with Niskin bottles during the first CTD Cast of the morning at 1, 7, 25, 35, 75, and 100 m depth. Phytoplankton taxonomy and density was determined at each depth at the level of species or genera. Values of zero are real and denote that a specific species was not found at that cruise/depth.
