A Role in Ocean Exploration?A Role in Ocean Exploration?
Minerals Management Service:
To manage the mineral resources on the OCS in an environmentally sound & safe manner and to timely collect, verify, and distribute mineral revenues from Federal and Indian lands.

Research Results Research Results • Currents at relevant depths can disperse larvae
across the entire upper continental slope.
• Upper depth limit for Gulf of Mexico chemosynthetic communities is between 400 and 500 meters.
• In contrast to rapid tube growth at hydrothermal vents, cold seep tubeworms grow very slowly.
• It is estimated that worms 2 meters in length are from 170-250 years old.

Chemosynthetic fauna associated with Gulf of Mexico hydrocarbon seeps are similar to those of hydrothermal vents.
