Visualization flow of water in a sponge - Aquarius Reef Base ; Fluorescein dye is used to visualize how water is absorbed at the outside and then exhausted by a sponge.The Caribbean barrel sponge, Xestospongia muta, is a large and common member of the coral reef communities at depths greater than 10 m, and has been called the “redwood of the deep”, due to its up to 2000 year lifespan as well as its size and color. Despite its prominence, high biomass and importance to habitat complexity and reef health, very little is know about the basic biology of this massive sponge, including rates of mortality and recruitment, reproduction, growth and age. Like reef corals, this sponge is subject to bleaching and subsequent mortality.
With support from NOAA's Aquarius Reef Base at UNCW, NOAA's Coral Reef Conservation Program, and the Florida Keys National Marine Sanctuary, a research group has been monitoring populations of X. muta in the Florida Keys since 1997.

Monitoring of sponge respiration - Aquarius Reef Bas Florida ; non-calcifying reef organisms like sponges will likely benefit from negative impacts to corals caused by ocean acidification and climate change; research data suggest that water passing through a filter feeding X muta sponge drops more than 0.01 pH units, a significant fraction of the 0.1 drop that has already resulted from the acidification of the ocean by the increase in atmospheric carbon dioxide in recent decades.; scientists try to understand how to distinguish local acidification processes, like that from sponge respiration, from the global scale changes now occurring around the world. Only in this decade have scientists fully realized the threat of global acidification to calcifying organisms such as corals. Marine scientists around the world are now attempting to provide the information that we need to both understand and manage this important problem; field work, experiments and scientific setups of the AUG 2011 Research Mission: Ocean Acidification: Controls on Reef pH; Principal Investigator: Dr. Chris Martens, UNC Chapel Hill

Divers near the station - Aquarius Reef Base Florida ; Aquanauts (nitrogen saturated divers from the habitat) swim from the station to their working place, which can be several hundered meters away from the station. The Aquanauts have no decompression limits in these depths. 3 High-pressure air supplied undersea stations located as far as 1000' away from the habitat, allowing divers to communicate to the habitat and refill their scuba tanks while working on nearby sandy or coral reef areas.
