This data was gathered for a study that was seeking to determine the relationship between the spatial distribution of non-residual metals and total mercury in surficial sediments with clay content, and to idenfity metal enrichment regions in the Gulf of Paria. Several of the sampling sites were specifically located at the mouths of rivers that empty into the Gulf of Paria in order to investigate the contribution from land based sources of pollution.

The sediment samples were taken in July and November/December 1998 were averaged to produce a single value for the wet season. The sediment samples taken in March and April 1999 were averaged to produce a single value for the dry season. The sediment attributes were then linked to the spatial locations provided by the Trimble GPS. withheld 20110929 15584900 ArcView 3.2 A Trimble GeoExplorer GPS was used to navigate to the selected locations. This device had an accuracy of 100 meters because differential correction was not possible due to the unavailability of a base receiver. 100m Version 6.2 (Build 9200) ; Esri ArcGIS 10.9.1.28388 200307_GOP_IMA_pWGS84_sediment_textures_at_sediment_sampling_stations_in_Gulf_of_Paria_in_wet_1998_dry_1999 619998.5 668627 1180424.5 1119946 1 -61.904704 -61.458257 10.676512 10.127846 1 1 -61.904704 -61.458257 10.676512 10.127846 This data was gathered for a study that was seeking to determine the relationship between the spatial distribution of non-residual metals and total mercury in surficial sediments with clay content, and to idenfity metal enrichment regions in the Gulf of Paria.
