Marine Benthic Habitats and Seabed Suitability Mapping for Potential Ocean Current Energy Siting Offshore Southeast Florida

Abstract

This study examines the legal framework for ocean current energy policy and regulation to develop a metric for assessing the biological and geological characteristics of a seabed area with respect to the siting of OCE devices, a framework of criteria by which to assess seabed suitability (seabed suitability framework) that can facilitate the siting, and implementation of ocean current energy (OCE) projects. Seafloor geology and benthic biological data were analyzed in conjunction with seafloor core sample geostatistical interpolation to locate suitable substrates for OCE anchoring. Existing submarine cable pathways were considered to determine pathways for power transmission cables that circumvent biologically sensitive areas. Suitability analysis indicates that areas east of the Miami Terrace and north of recently identified deep-sea coral mounds are the most OPEN ACCESS J. Mar. Sci. Eng. 2015, 3 277 appropriate for OCE siting due to abundance of sand/sediment substrate, existing underwater cable route access, and minimal biological presence (i.e., little to no benthic communities). Further reconnaissance requires higher resolution maps of geological substrate and benthic community locations to identify specific OCE development locations, classify benthic conditions, and minimize potentially negative OCE environmental impacts.

Spatial Variability of Soil Physical Properties Based on GIS and Geo-Statistical Methods in the Red Beds of the Nanxiong Basin, China

“…Due to the interpolation of available observations, this makes the method independent of trends and offers hope for a significant expansion of the application areas [26]. Although EBK was successfully used for analysis of humus distribution [26] and in benthos mapping [27], few scholars have used this method to study the spatial variability of soil. Thus, this study attempts to apply the OK and EBK methods in a comparative study of soil physical properties in order to explore the best research methods to study the spatial variation of soil properties at a fine scale.…”
