History repeats: a demand-supply price case study of the 19th century Diamond-back terrapin population collapse
Increasing demand for turtles in the Chinese and Indonesian food markets is leading to severe decline in several Southeast Asian species and an accompanying increase in freshwater turtle imports from the US. The Diamondback ...
High degree of connectivity among amphi-Atlantic populations of Hermodice carunculata (Amphinomidae, Annelida)
Polychaete annelids in the genus Hermodice exhibit an amphi-Atlantic distribution extending into the Gulf of Mexico as well as the Caribbean and Mediterranean Seas. Currently, this genus contains two nominal species; H. ...
Modular carbon fiber propeller
Utilization of Composite Materials with Marine Applications
Multi-purpose telescopic boom crane
The Goal of our Project is to design a crane that serve the purpose of both lifting cargoes on and off a vessel, and also as a gangway to transfer personnel from one vessel to another.
What does Holocene organic matter deposition in a Bahamian Bluehole reveal about internal basin environmental change?
Blueholes and sinkholes are ubiquitous in the tropics, and their sediment preserve records of environmental change. There is a poor understanding of how environments in blueholes change during Holocene sea-level rise. ...
Identifying Limiting Nutrients in Galveston Bay Seagrass CommunitiesIdentifying Limiting Nutrients in Galveston Bay Seagrass Communities
Seagrasses, an ecologically important group of marine plants, have declined in worldwide areal extent by 29% since 1879, in part due to nutrient enrichment. To reduce this decline, it is important to discover the limiting ...
Dark side of birding: perceptions of bird watching's negative ecological impacts
Birders, in the pursuit wild birds, can negatively impact birds and critical bird habitat. Often, competition for space or resources can create conflict among recreational users and bird conservation initiatives. This study ...
Offshore natural gas hydrate harvesting system
The purpose of this project is to design a system that will allow for production of methane gas from a deep-sea Methane Hydrate Harvester. A satellite host system was chosen in a feasibility report, released in September ...
Effects of pelagic larval duration on the geographic population structure of two sipunculan species in the Sea of Japan
This study examines genetic diversity in two species of sipunculan worm, Phascolosoma agassizii and Themiste pyroides, in the Sea of Japan. Low sea levels of the Pleistocene era partially or completely isolated marginal ...
Eurythoe complanata: more cryptic species in the Pacific?
Mitochondrial DNA data has shown that Eurythoe complanata is a cryptic species complex characterized by deeply divergent sympatric populations in the Atlantic, and on either side of Panama, despite almost no morphological ...
