Presence/Absence And Density Data For Epipelagic Tows Collected During R/V Blazing Seven Cruises Lf2016a And Lf2016b, Northern Gulf Of Mexico From 2016-06-09 To 2016-07-28, Jay R. Rooker, David Wells Jul 2018

Presence/Absence And Density Data For Epipelagic Tows Collected During R/V Blazing Seven Cruises Lf2016a And Lf2016b, Northern Gulf Of Mexico From 2016-06-09 To 2016-07-28, Jay R. Rooker, David Wells

DEEPEND Datasets

This dataset reports presence/absence and density data for epipelagic tows collected in the northern Gulf of Mexico during R/V Blazing Seven cruises LF2016A and LF2016B (2016-06-09 to 2016-07-28). Larval fishes were sampled from 48 stations and cruise data were collected at each site including latitude/longitude, date, time, environmental data (temperature, salinity, dissolved oxygen) and Sargassum dry weight. Larval catch data before and after the oil spill will be compared to improve our understanding of the causes of temporal variability as it relates to the Deep-Water Horizon oil spill (DWHOS). Habitat associations of selected taxa (billfishes, tunas, dolphinfishes, flyingfishes) will be …


Habitat Classification Of The Gulf Of Mexico (Gom) Using The Hybrid Coordinate Ocean Model (Hycom) And Salinity/Temperature Profiles, Cruises Dp01-Dp04, May 2015 To August 2016, Matt Johnston, Rosanna Milligan, Cole Easson, Sergio Derada, Brad Penta, Tracey Sutton Jan 2018

Habitat Classification Of The Gulf Of Mexico (Gom) Using The Hybrid Coordinate Ocean Model (Hycom) And Salinity/Temperature Profiles, Cruises Dp01-Dp04, May 2015 To August 2016, Matt Johnston, Rosanna Milligan, Cole Easson, Sergio Derada, Brad Penta, Tracey Sutton

DEEPEND Datasets

Deep pelagic habitat from the entire Gulf of Mexico (GOM) was classified using the deviation of sea surface height (SSH) from mean SSH for the entire GOM and water temperature at 300 m water depth, founded on ocean condition data from the 1/25° GOM HYbrid Coordinate Ocean Model (HYCOM). Pelagic habitats were segregated into anticyclonic, mixed boundaries, and common water units – all of which likely produce varying levels of forage for deep-sea fauna and may be trophic drivers. Model classifications were compared to classifications based on water column temperature and salinity at depth, as measured by CTD casts during …


Presence/Absence And Density Data For Epipelagic Tows From 48 Stations In The Northern Gulf Of Mexico From R/V Blazing Seven Cruises Lf2015a And Lf2015b June 2015 And July 2015, Jay R. Rooker, R.J. David Wells Mar 2017

Presence/Absence And Density Data For Epipelagic Tows From 48 Stations In The Northern Gulf Of Mexico From R/V Blazing Seven Cruises Lf2015a And Lf2015b June 2015 And July 2015, Jay R. Rooker, R.J. David Wells

DEEPEND Datasets

Larval catch data after the oil spill is being used to improve our understanding of the causes of temporal variability as it relates to the Deep Water Horizon oil spill (DWHOS). Bongo and neuston net tows were conducted at 48 stations in both June and July, 2015 in the northern Gulf of Mexico. Cruise data collected at each site included latitude/longitude, date, time and environmental data (temperature, salinity, dissolved oxygen). The occurrence and density of selected epipelagic (e.g., billfishes, tunas, dolphinfishes, flyingfishes) and deep pelagic (e.g., lanternfishes, bristlemouths, marine hatchetfishes) fish larvae were quantified and are being used to extend …


Chlorophyll Concentration And Optical Absorption Spectra Of Particulate And Dissolved Material, Collected At Several Depths On Deepend Cruises Dp03 And Dp04 From January-December 2016, Chuanmin Hu, Jenifer Cannizzaro, David English Mar 2017

Chlorophyll Concentration And Optical Absorption Spectra Of Particulate And Dissolved Material, Collected At Several Depths On Deepend Cruises Dp03 And Dp04 From January-December 2016, Chuanmin Hu, Jenifer Cannizzaro, David English

DEEPEND Datasets

The optical absorption spectra from seawater’s particulate and dissolved components can be used to compute the penetration of light to various depths, estimate the proportion of living to non-living particulate matter, assess photosynthetic light availability and the type of phytoplankton present, and the validate of satellite or airborne ocean color measurements. Chlorophyll and phaeopigment concentrations are often used to estimate the amount of phytoplankton present, and to allow extrapolation of in situ fluorometric measurements. Water was collected using a CTD rosette near the surface and from several depths at each sampling station occupied by the DEEPEND cruises DP03 & DP04 …


Inventory Of Gulf Oceanic Fauna Data Including Species, Weight, And Measurements. Cruises Dp01 May 1-8, 2015 And Dp02 August 9-21, 2015 R/V On The Point Sur In The Northern Gulf Of Mexico, April Cook, Tracey Sutton Feb 2017

Inventory Of Gulf Oceanic Fauna Data Including Species, Weight, And Measurements. Cruises Dp01 May 1-8, 2015 And Dp02 August 9-21, 2015 R/V On The Point Sur In The Northern Gulf Of Mexico, April Cook, Tracey Sutton

DEEPEND Datasets

This data set includes the biological and environmental data for all of the species collected during the DP01 (May 2015) and DP02 cruises (August 2015). The main gear type used was a 10-m2 Multiple Opening Closing Net and Environmental Sensing System (MOCNESS). The MOCNESS was fitted with 6 nets which were opened according to the following depth scheme: net 0 from the surface to 1500m, net 1 from 1500-1200m, net 2 from 1200-1000m, net 3 from 1000-600m, net 4 from 600-200m, and net 5 from 200m to the surface. Two trawls were conducted at each station sampled to capture diel …


Cruise Data For Neuston Net And Paired Bongo Net Tows From 48 Stations In The Northern Gulf Of Mexico From R/V Blazing Seven Cruises Lf2015a And Lf2015b June 2015 And July 2015, Jay R. Rooker, R.J. David Wells Feb 2017

Cruise Data For Neuston Net And Paired Bongo Net Tows From 48 Stations In The Northern Gulf Of Mexico From R/V Blazing Seven Cruises Lf2015a And Lf2015b June 2015 And July 2015, Jay R. Rooker, R.J. David Wells

DEEPEND Datasets

Shelf and slope waters in the Deep Water Horizon oil spill (DWHOS) area are known to serve as critical spawning, nursery, and foraging habitat of several important oceanic species including billfishes (e.g. blue marlin, white marlin, sailfish), tunas (bluefin tuna, yellowfin tuna), and other pelagic taxa (swordfish, dolphinfishes). The aim of this component was to further investigate potential ecological effects of the DWHOS on pelagic fishes during the early life period. Larval fishes were sampled from 48 stations in the northern Gulf of Mexico and cruise data was collected at each site including latitude/longitude, date, time and environmental data (sea …
