GENERAL THEMES OF CONFERENCE

NEW! Submerged landscapes and archeology:  around the globe, Quaternary sea level was significantly lower than present for approximately 90 % of this time, as a consequence of glacial-interglacial climate cycles. The seaward progression of coastlines associated with sea-level regressions exposed what is now the submerged continental shelf as a terrestrial ecosystem. Within some epicontinental seas interaction of tectonic and climate change (e.g. postglacial isostatic rebound and eustatic sea-level rise) accentuated high amplitude Holocene relative sea-level changes. Submerged landscape studies, relying on high-resolution geophysical and hydrographic data, have enlightened ancient habitats occupied by our early ancestors, to reveal areas of the continental shelf where prehistoric occupation sites preserved during sea-level rise. This session seeks to focus on submerged landscape reconstruction and the mapping and sampling tools utilized to elucidate information on hominin evolution.

Shelf and deep-sea habitats: This session to include deep-water methods, technological advances, and discussion of specific shelf and deep-sea habitats, as well as how their distribution and specific characteristics may play an important role at broader scales. Talks may include habitat mapping on the shelf and in the deep-sea for conservation and management purposes.

Coastal and shallow water habitats: This session will have a particular focus on linking methodologies from terrestrial remote sensing (including the emergence of aerial drones) to shallow water environments.  Talks may include habitat mapping in coastal and shallow water habitats for conservation and management purposes.

Mapping, planning, and impact assessment for ocean energy: This session will focus on the use of seafloor mapping technologies and case studies associated with marine renewable and conventional energy.

Marine Minerals: This session will focus on habitat issues related to marine minerals development including aggregates and deep-sea minerals (e.g. seafloor massive sulfides, polymetallic nodules).

Deep-water coral habitats: For presentations about coral habitat discovery, significance, and management.

Seeps and Hydrates: Talks about mapping and understanding seeps, gas hydrates, and the chemosynthetic ecosystems fueled by release of methane at the seafloor.

Interactions between oceanographic processes and habitats. This session will focus on geologic-habitat and biotic-habitat change and presence-absence as a function of bathymetric position, currents, waves, and water chemistry.
