Depth Records

Lac bay depths (GIS)

Depth of Lac Bay in meters. Data acquired with lowrance HDS7 Gen 3 Totalscan transducer. The borders are not realiable. No map to snap to the coast/borders was available.

  • Microsoft Excel file (longitude, latitude, depth in feet) [original file]
  • Line shape file (*.shp) with depth isolines (m)
  • Geotiff at a resolution of 2x2 m. The original file was interpolated using Inverse Distance Weighting (IDW) with a maximum number of 12 points for a single cell value. Interpolation boundaries at 30 meter from any given point.

Legend:

  • -0.5 m    light yellow
  • -5 m       green 
  • -13.5 m  dark blue

High coral cover at lower mesophotic depths: a dense Agaricia community at the leeward side of Curaçao, Dutch Caribbean

Coral cover at lower mesophotic depths (particular- ly >75 m) by zooxanthellate scleractinians is usually very scarce, largely due to the extremely low irradiance levels at these depths. An exception are the Leptoseris communities observed near the Hawaiian islands (Central Pacific) that form dense fields, supporting a broad range of associated organ- isms. Here, we describe a similar high-cover coral community at lower mesophotic depths, but in the Caribbean. The com- munity was observed on the leeward side of Curaçao (Southern Caribbean) using a manned submersible (Curasub), and was predominantly composed of plating Agaricia corals and an assemblage of reef fishes. Some of the fish species were known from similar depths at other lo- calities, whereas others obtained new depth records. Future surveys are required to establish the extent of similar high- coral communities around Curaçao, and more broadly in the western Atlantic.
