We present a multi-modal approach consisting of multibeam bathymetry, video, and still imagery that collectively provides the knowledge base necessary to perform impact assessments in glacial moraine habitats largely composed of hard substrata.

The submerged parts of offshore wind farms (OWFs) act as artificial reefs, providing new habitats and likely affecting fisheries resources. In this paper we focus on how the artificial reefs established by OWFs affect ecosystem structure and functioning.

Organic matter (OM) production and degradation is important in coastal estuaries, and OM fate is strongly influenced by the coupled interactions of bioturbation and biogeochemistry. From April to September 2013 sediment cores and a benthic observing system, Wormcam, were used to investigate the in situ relationship of biogeochemistry and macrofauna bioturbation in Cape Lookout Bight North Carolina.

The first bay-wide synoptic survey of benthic habitat quality in Narragansett Bay, Rhode Island, USA, was conducted in August of 1988. Twenty years later, we revisited the same sampling locations as the original survey using similar sediment profile imagery technology and analysis tools.

A detailed map and dataset of sedimentary habitats of the Milford Haven Waterway (MHW) was compiled for the Milford Haven Waterway Environmental Surveillance Group (MHWESG) from seafloor images collected in May, 2012 using sediment-profile and plan-view imaging (SPI/PV) survey techniques.

Sediment profile imaging (SPI) technology has been used in some form since 1969 to investigate the structure and appearance of near-surface aquatic sediments.

Documentation of long-term change in benthic ecosystems is important for assessing and managing the effects of change.

Ten years ago, sediment profile photography was proposed as an efficient technique for in situ documentation of organism-sediment relations (Rhoads and Cande, 1971). This technique has not gained wide acceptance because it was not supported by theory to interpret sediment profile images.
