Science objectives

The primary objective of the SeepC Project is to advance our general knowledge of connectivity in the deep sea using taxa found at seeps as model systems. The focus is on species and processes occurring in the Intra-American Sea (including the Caribbean, Gulf of Mexico, and eastern seaboard of the US), with attention to oceanographic circulation, life histories, and genetics.  Questions that apply in shallow-water systems motivate this study:

  1. What phylogeographic breaks occur in the system? It is important to distinguish between phylogeography and connectivity.  A phylogeographic break implies a long history of isolation or possibly cryptic speciation, while genetic population structure indicates gene flow is reduced, but still ongoing or recent. 
  2. Do collections from different sites indicate a panmictic population of a given species?  This is the fundamental question about connectivity and the scale of population genetic variation in marine species with planktonic larvae and it comprises extent of gene flow, directionality, and relative contributions.
  3. What bio-physical processes underlie observed connectivities?  Biological processes (e.g., larval distributions in the water column, timing of reproduction, and planktonic larval duration) and physical processes of transport and dispersion interact to determine connectivity.

Our efforts include improving the oceanographic model for the IAS near the seabed using current data from moorings at several depths and locations and coupling this model to a Lagrangian larval transport model.  We stress the importance of iterative interactions among the science teams to advance our understanding of connectivity in the deep sea through descriptive and hypothesis-driven research.   We will develop effective and best methods for hypothesis testing under the constraints of working in a relatively inaccessible environment and will build capacity in understanding connectivity in deep-sea systems.

NEW SITES OF INTEREST:

1) Two mooring recoveries

Brine Pool NR1
Released 11/5/13, 0830
27deg43.394'N, 091deg16.753'W

Alaminos Canyon
Released 11/6/13, 1448
26deg21.300'N, 095deg29.799'W

Each of the train wheel anchors has wood and bone bags to be recovered as well as a 4-tube larval trap.   Both moorings use non-impolodable volume floats (syntactic foam or plastic).  The Brine Pool mooring also has a small float with a small spar and orange flag for visibility at the surface. 

2) One Mooring deployment (Florida Escarpment)
similar configuration as those recovered

3) Alvin seep sampling
mussels, clams, tubeworms, and associated animals; targeting at least 30 individuals per species (manips, net, slurp) 

4) Sentry plankton sampling 
Strategies TBD in consultation with Sentry team, but perhaps a series of pump runs directly above seep sites (lowest possible altitude; sampling a constrained area, on the order of 100 m x 100 m (?); multiple heights above bottom (lowest, 10 m, 50 m, 100 m etc?)

5) MOCNESS tows
Strategies TBD - would be great to plan a simple experiment to compare Sentry and MOCNESS

6) Sentry high-resolution mapping of Fl Esc wall

7) Sentry high-resolution maps of all seep areas (imaging and bathymetry)

8) CTD casts

9) XBTs

10) Hydrophone
