CT24B:
Using Trophic Tracers (e.g., Fatty Acid or Stable Isotope Signatures) to Study Oceanic Interfaces Posters


Session ID#: 9346

Session Description:
To complement the overall theme (Ocean Sciences at the Interface) of this ASLO conference, we invite presentations on research that involves the utilization of tracers such as fatty acids or stable isotope ratios to address questions about trophic ecology at oceanic interfaces. Relevant ecological interfaces may include those formed by the meeting of sediment and water, land and sea, sea and air, sea and estuary, converging currents, etc. In expanding our knowledge on the trophic connections across boundaries, we will better understand the broader topic of connectivity in the world’s oceans. We invite seminars that a) utilise one or more tracer methods to address some aspect of trophic ecology (ranging from microbes to mammals) involving interfaces, and b) improve our knowledge of the larger implications of trophic connections between oceanic habitats.
