Sediment cores (up to 6 m in length) from the bottom of Blue Hole, a 125 deep Pleistocene sinkhole located lagoon Lighthouse Reef Atoll, Belize, consist undisturbed, annually layered biogenic carbonate muds and silts with intercalated coarser grained storm beds. The sedimentation rate sections is 2.5 mm/y on average, long span past 1500 years. Oxygen isotopes laminated sediment provide late Holocene climate proxy: A high-resolution δ18O time series traces final Migration Period Pessimum,...
Brucite [Mg(OH)2] microbialites occur in vacated interseptal spaces of living scleractinian coral colonies (Acropora, Pocillopora, Porites) from subtidal and intertidal settings the Great Barrier Reef, Australia, Montastraea Florida Keys, United States. encrusts microbial filaments endobionts (i.e., fungi, green algae, cyanobacteria) growing under organic biofilms; brucite distribution is patchy both within coralla. Although undersaturated seawater, its precipitation was apparently induced...
The Barrier Island Comprehensive Monitoring (BICM) program was implemented under the Louisiana Coastal Area Science and Technology (LCA S&T) office as a component of System Wide Assessment (SWAMP) program. BICM project developed by State (Coastal Protection Restoration Authority [CPRA], formerly Department Natural Resources [DNR]) to complement other coastal monitoring programs such Coastwide Reference System-Wetlands (CRMS-Wetlands) collaborative research effort CPRA, University New Orleans...
Land loss and seafloor change around the Mississippi Alabama (MS-AL) barrier islands are of great concern to public local, state, federal agencies. The provide wildlife protected areas recreational land, they serve as a natural first line defense for mainland against storm activity (index map on poster). Principal physical conditions that drive morphological coastal in this area include decreased sediment supply, sea-level rise, storms, human activities (Otvos, 1970; Byrnes others, 1991;...

Wave-induced sediment transport induced island migration, landward retreat, inlet evolution. These processes can be measured using repeat bathymetric surveys to analyze elevation time. This...

While deep-sea coral habitats have been discovered within each ocean basin, knowledge about the ecology these associated inhabitants continues to grow. This report presents information results from Lophelia II project that examined in Gulf Mexico....
As part of the Barrier Island Evolution Research project, scientists from U.S. Geological Survey St. Petersburg Coastal and Marine Science Center collected sediment samples northern Chandeleur Islands in March September 2012. The overall objective this which integrates geophysical (bathymetric, seismic, topographic) sedimentologic data, is to better understand depositional erosional processes that drive morphologic evolution barrier islands over annual interannual timescales (1 5 years)....
Scientists from the U.S. Geological Survey (USGS), St. Petersburg Coastal and Marine Science Center (SPCMSC), in collaboration with Army Corps of Engineers (USACE), conducted geophysical sedimentological surveys around Cat Island, westernmost island Mississippi-Alabama barrier chain (fig. 1). The objectives study were to understand geologic evolution Island relative other islands northern Gulf Mexico identify relationships between history, present day morphology, sediment distribution.

In collaboration with the U.S. Army Corps of Engineers, scientists from Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center collected over 487 line kilometers (> 300 miles) high-resolution geophysical data around Cat Island, Mississippi, to improve understanding island's geologic evolution identify potential sand resources for coastal restoration. addition, 40 vibracores were on island, generating more than 350 samples grain-size analysis. The results indicate that...

As part of the Barrier Island Evolution Research project, scientists from U.S. Geological Survey St. Petersburg Coastal and Marine Science Center conducted nearshore geophysical surveys off northern Chandeleur Islands, Louisiana, in June 2011. The overall objectives study are to better understand barrier-island geomorphic evolution, particularly storm-related depositional erosional processes that shape islands over annual interannual timescales (1-5 years). Collection data will allow us...
