Title of thesis: INFLUENCES OF WAVE CLIMATE AND SEA LEVEL ON SHORELINE EROSION RATES IN THE MARYLAND CHESAPEAKE BAY Jia Gao, Master of Science, 2015 Thesis directed by: Professor Lawrence P. Sanford, University of Maryland Center for Environmental Science (UMCES) SWAN and a parametric wave model implemented by the Chesapeake Bay Program (CBP) were used to simulate wave climate from 1985 to 2005...
The striped bass (Morone saxatilis) is an economically and ecologically important finfish species along the Atlantic seaboard of the United States. Recent stock assessments in Chesapeake Bay (U.S.A.) indicate that non-fishing mortality in striped bass has increased since 1999, concomitant with very high (>50%) prevalence of visceral and dermal disease caused by Mycobacterium spp. Current fisher...
Mosquito larval surveillance for environmental monitoring and pest-control purposes was conducted monthly at dredged soil-dumping areas during the construction of a new harbor in Yongcheon Bay, approximately 5 km SE of Jinhae, on the SW side of Namsan (Mt. Nam) and across the bay from Su-do (Su Island) in Gyeongsangnam Province, Republic of Korea (ROK) from November 2007 through April 2008. Dur...
The delineation of lateral and vertical gradients of organic contaminants in lakes is hampered by low concentrationsand nondetection of many organic compounds in water. Passive samplers (semipermeable membrane devices [SPMDs] and polar organic chemical integrative samplers [POCIS]) are well suited for assessing gradients because they can detect synthetic organic compounds (SOCs) at pg L(-1) con...
Samples of liver and kidney of Little Blue Heron (Egretta caerulea) collected on Sepetiba Bay, Rio de Janeiro, Brazil, were analysed for their copper, zinc, cadmium, lead, chromium and nickel content. Mean concentration levels in liver and kidney (μg.g dry weight) were 6.32955 and 6.57136 (Cd); 78.17409 and 96.89409 (Zn); 44.01727 and 65.20864 (Cu); 41.15091 and 39.62318 (Pb); 2.80091 and 4.164...
This paper proposes a robust navigation method for Autonomous Underwater Vehicles (AUVs) operating around structures such as harbors and breakwaters. This method consists of a state estimator and a motion controller, enabling localization in the configuration map as well as following pre-given waypoints without any external help. The state estimator is based on a “particle filter” where the veh...
This work describes the water collection experiment component of the Megacollect 2004 campaign. Megacollect was a collaborative campaign coordinated by RIT with several institutions to spectrally measure various target/background scenarios with airborne sensors and ground instruments. An extension to the terrestrial campaign was an effort to simultaneously measure water optical properties in di...
Guanabara Bay is the second largest bay in the coast of Brazil, with an area of 384 km(2). In its surroundings live circa 16 million inhabitants, out of which 6 million live in Rio de Janeiro city, one of the largest cities of the country, and the host of the 2016 Olympic Games. Anthropogenic interference in Guanabara Bay area started early in the XVI century, but environmental impacts escalate...
Long-term measurements (i.e. months) of in situ pH have not previously been reported from the Arctic; this study shows fluctuations between pH 7.5 and 8.3 during the spring bloom 2012 in a coastal area of Disko Bay, West Greenland. The effect of acidification on phytoplankton from this area was studied at both the community and species level in experimental pH treatments within (pH 8.0, 7.7 and...
The Antarctic Chilean peninsula, is characterized for being stable in its oceanographic conditions. Nevertheless, its coastal zones, such as bays, may have more variable physical conditions, both spatially and temporally. It has been observed that a remarkable interaction between the oceanographic conditions and spatial distribution patterns of zooplankton occurs. However, there is no good unde...
