Biodiversity and ecosystem functioning
This session welcomes any papers that examine any aspect of biodiversity and/or function of deep-sea ecosystems.
Topics of food webs and community ecology (but see also the special Pelagic Food Webs session below)
Midwater and water-column organisms and ecosystems, including planktonic, gelatinous, and nektonic fauna. (See also the Pelagic Food Webs special session below)
This session welcomes presentations that address any aspect of the study, conservation or management of deep water corals communities, including population connectivity, physiology, trophic ecology, community structure, biogeochemical studies, restoration methods and the development of novel research tools.
Seamounts and canyons
Habitat-based studies including seamounts, ridges, canyons
Ecosystems in and around vents, seeps, and organic falls, and the symbioses therein
Deep-ocean observing systems
This session welcomes any papers that explore innovative techniques and novel approaches to observing biology and ecosystem variables in the deep ocean. Of particular interest are cross-cutting technologies that combine scientific and engineering approaches to provide a synoptic view of a given biological process taking into account the physicochemical variables affecting it. This session will provide a showcase for studies advancing scientific techniques, technological development, and data processing and sharing, contributing to observations in the deep sea across all levels of biological organization (genes, species, populations, communities…).
Advances in taxonomy and phylogeny
This session welcomes any papers that look at aspects that cut across habitat/ecological
boundaries in the realm of evolutionary biology, systematic biology, phylogeography,
biogeography as well as new methodologies or approaches on alpha-taxonomy.
This session welcomes any papers that examine the biology and ecology (in its widest sense) of
individual species from any deep-sea environment. The presentation does not have to be limited
to one species but can look in detail at any species of interest.
Connectivity and biogeography
This session welcomes any papers that focus on recent advances on the understanding of
population connectivity and species distribution in the deep sea, including the processes that
control connectivity and modulate biogeography, empirical estimates, and modeling efforts.
Natural and anthropogenic disturbance
This session welcomes any papers that discuss results from studies examining the vulnerability,
resilience, and response of organisms to the impact of natural disturbance (e.g. cascading and
turbidity events along slopes and volcanic eruptions), climate change, or human activities.
Deep-ocean stewardship challenges, opportunities, and solutions
This session welcomes any papers that discuss current or proposed stewardship issues in our deep oceans raised by activities such as mining (SMS, nodules, cobalt crusts, phosporites, etc), fisheries, oil and gas, deep-sea tailings placement, and marine genetic resources.
Deep-sea ‘omics: concepts and applications –Omics
This session welcomes any papers that focus on current and future research trends in deep-sea
-omics aimed at: (i) advancing knowledge of organismal biology, environmental diversity, and
ecosystem functioning and evolution, (ii) complementing results of traditional taxonomy and
community structure analyses, and (iii) developing systematic sampling and structured
frameworks for large-scale studies. This session is open to any research involving –omic
approaches, as well as topical perspectives, ideas, and initiatives.
Interdisciplinary functional biology of deep-sea organisms: a tribute to James J. Childress
This session welcomes any contributions that are inspired or influenced by Jim Childress’ work, that reveal unique adaptations, behaviors and interactions of deep-sea organisms. The
pioneering studies of biologist James Childress integrated ecology, evolution, oceanography,
biochemistry, physiology and engineering for over fifty years to generate novel insights into
elusive deep-sea organisms and the pelagic, benthic, and hydrothermal vent ecosystems in
which they live. Childress worked relentlessly to overcome real and perceived barriers to
exploration so that the deep sea may be put into proper perspective and treated with
Mining impacts in the deep sea
This session welcomes any contributions from research on mining impacts in the deep sea with
a focus on the Clarion Clipperton Zone (CCZ), but research from other regions would be
welcome. The CCZ in the central Pacific Ocean is currently the most active frontier for deep-sea mineral exploration in international waters. Recent contractor-led, European Union, NOAA, and private-foundation funded projects in the CCZ have started to make available considerable new data on the taxonomy, ecology, population connectivity, and potential resilience of the fauna to mining activity. In this session, we invite colleagues with new data from any of these programs and/or other areas to share their new findings and discuss the results.
