The Caernarvon Diversion meters Mississippi River water into coastal marshes of Breton Sound. Elevated levels of nitrogen in river water have sparked concerns that nutrient loading may affect marsh resilience and belowground biomass, as evidence from several marsh fertilization studies. These concerns resulted from observation that fresh and brackish Breton Sound marshes suffered extensive damage from Hurricane Katrina. The goal of this study is to determine the fate of nitrate (the dominant ino...

Louisianas coast is losing land due to erosion at the startling rate of approximately 24 square miles per year (Lockwood & Gray, 2005). Coastal erosion has serious implications for human safety and Louisianas economy. There are many environmental education programs throughout coastal regions of the United States that educate school children about coastal issues. LSU Coastal Roots (CR) is one such program. Students at approximately 40 participating schools raise native plants in nurseries at thei...

Louisianas estuaries and coastal waters play an important role in providing habitat for several estuarine-dependent species and also serve as a nursery for the juveniles of several other species. The current rate of land loss in Louisiana and the decline of estuarine-dependent species force us to improve our understanding of the recruitment of these species into Louisianas estuaries. Habitat suitabilities were developed for several fish species of concern (SOC) and other estuarine-dependent spec...

Hurricanes account for a significant portion of damages, injuries, and fatalities in the Caribbean. The Dominican Republic has had 3 major hurricane strikes in this century resulting in loss of lives for thousands of people and billions of US $ in economic loss. Major hurricanes had been relatively infrequent in north-eastern Nicaraguas modern history until Hurricane Felix, a Category 5 storm, made landfall in the north-east in 2007. It caused 130 confirmed deaths and brought devastation to many...

Coastal erosion is a serious problem that directly affects Louisiana and indirectly affects the entire United States. Between 1990 and 2000, Louisiana lost 24 square miles of land per year, which equals an approximate football field lost every 38 minutes (Barras, Bourgeois, & Handley, 1994). Hurricanes Katrina and Rita in 2005 accelerated this land loss by transforming 217 square miles of marsh into open water (United States Geological Survey, 2006). As a leader in seafood, oil, and gas producti...

Louisianas coastal wetlands provide a habitat for diverse wildlife, recreational opportunities for Louisiana residents and tourists, and an important natural buffer between communities and powerful hurricanes. Because they are disappearing at a rapid rate, coastal wetlands issues have been prominent in south Louisiana for decades. The catastrophic hurricanes of 2005 and 2008 have given the discussion an increased sense of urgency. Through this paper, I explore coverage of wetlands loss in local ...

Storm surge is an abnormal rise of the sea surface caused by atmospheric forcing, including the wind stress and atmospheric pressure associated with extra-tropical and tropical cyclones. Hurricanes and typhoons have a great impact on coastal regions, and can cause severe loss of lives and great damages. A systematic investigation of storm surge impact to the coasts of Louisiana and Texas, where the continental shelf reaches up to 200 km in width, is conducted here using the hydrodynamics Finite-...

Recent hurricane events in coastal Louisiana have emphasized the severe vulnerability of medical special needs (MSN) patients during flood disasters. MSN populations may be comprised of hospital, nursing home or hospice patients; the physically or mentally disabled; medically-dependent individuals requiring life-sustaining equipment or medicines; and frail elderly. Over 150 hospital and nursing home fatalities resulted from Hurricane Katrina in New Orleans. More than four hundred elderly over th...

Marsh terracing is an innovative restoration technique being used in shallow, open water marshes in coastal Louisiana. When properly constructed and planted with an applicable plant species, terraces promote sediment deposition and accumulation by reducing wave energy. Although used extensively for marsh creation, little published information is available on techniques for establishing vegetation on marsh terraces. The goal of this research was to determine the optimal planting season and most e...

Use of bioremedial technologies has gained popularity in recent decades for application at oil spill sites. While much research has been done on specific case studies along marine shores, such as with the spill of the Exxon Valdez, there still remain questions as to the advantage of active biological treatment vs. natural attenuation in freshwater environments. To examine this question, a comparative study of allochthonous and autochthonous microbial communities ability to degrade weathered oil ...

Terracing is a novel technique used to combat coastal marsh loss in Louisiana and Texas. Terraces are assumed to slow marsh erosion, decrease pond depth, and encourage vegetation expansion. Terraced ponds have never been evaluated as habitat for waterbirds, which heavily depend on Louisiana�s coastal marshes. From April 2005 to April 2006, I monitored waterbird species richness and density through time to estimate effects that terracing has on habitat quality. Water quality (turbidity, salinit...

The development of reliable tools for identifying essential fish habitat (EFH) has proven problematic. Knowledge of the distribution and biomass of fishes over discrete habitat types is a prerequisite for effective use of EFH in the management of important commercial and recreational fish species. Resolution of the influence of habitat type and environmental factors on the distribution of fishes is confounded by limitations of traditional sampling gears. To date, hydroacoustic technology has bee...

The Twiggs Clay is an upper Eocene claystone found as discontinuous deposits downdip of the Fall Line in the Coastal Plain Province of eastern and central Georgia. A distinctive facies of the Twiggs is found in two lenses near the town of Wrens. The nature, origin, and potential commercial application of this resource are examined. Four strata and two mineralogic assemblages are recognized in the Wrens deposit. The lower three strata are near white in color and very low in density. These strata ...

Few people realize that in Louisiana land is lost to open water at about a rate of 24 square miles a year, faster than anywhere else in the world (Barras, Beville, Britsch, Hartley, Hawes, Jonston, Kemp, Kinler, Martucci, Porthouse, Reed, Roy, Sapkota, & Suhayda, 2003). Not only is the public low to moderately environmentally literate, there is a need to reach students early on to ensure the greatest benefit. This is the main reason why Louisiana Sea Grant¡¦s Coastal Roots Wetland Seedling Nurse...

Large summertime proliferations (or blooms) of the noxious filamentous cyanobacterium Lyngbya majuscula have been observed in the coastal marine waters of Moreton Bay, Queensland. This photosynthetic organism is believed to have a high iron requirement and preliminary studies have shown that the presence of organically complexed iron stimulates growth. Since there is no evidence that Lyngbya produces siderophores to aid iron acquisition, it has been hypothesized that this organism may acquire ir...

The high productivity of Eastern Boundary Upwelling Ecosystems (EBUE), some of the most productive ecosystems in the globe, is attributed to the nutrient rich waters brought up through upwelling. Climate change scenarios for coastal upwelling systems, predict an intensification of coastal upwelling winds. Associated with intensification in upwelling are biogeochemical changes such as ocean hypoxia and ocean acidification. In recent years, the California Current System (CCS) has experienced the o...

Current riparian management objectives in the Pacific Northwest promote both retention of existing conifers and conversion of hardwood-dominated areas to conifers. Although understanding of relationships between riparian vegetation and salmonid prey availability is growing, temporal variation in these relationships is poorly understood. Seasonal fluxes in availability of aquatic and terrestrial invertebrate prey for coastal cutthroat trout (Oncorhynchus clarki clarki) were investigated by estima...

Genetic diversity of two salmonid species, Dolly Varden (Salvelinus malma) and coastal cutthroat trout (Oncorhynchus clarki clarki) in Prince William Sound, Alaska were examined at multiple spatial scales with three molecular markers. Pleistocene glaciers covered what is now Prince William Sound 8,000- 12,000 years ago and both species colonized the region subsequently. Because these species have different migratory behavior and historic ranges I expected to see different patterns of genetic div...

An inexpensive method for calibrating an infrared analyzer to measure varying ranges of carbon dioxide partial pressures (Pco₂) is described. A discussion is made of the hydrographic (temperature, salinity, and sigma-t) and chemical (dissolved oxygen, AOU, Pco₂ pH, and nutrients) variables that were observed along the Newport hydrographic line in March and June 1971. A winter storm in late March led to an inshore feature of doming isolines. Indications of early seasonal upwelling and photosynthe...

Biological invasions provide a unique opportunity to study the mechanisms that regulate community composition and ecosystem function. Invasive species that are also ecosystem engineers can substantially alter physical features in an environment, and this can lead to cascading effects on the biological community. Aquatic-terrestrial interface ecosystems are excellent systems to study the interactions among invasive ecosystem engineers, physical features, and biological communities, because intera...

Understanding how large-scale processes (>100 kms) influence ecological communities is currently a major focus in ecology. In marine systems, coastal upwelling, a large-scale oceanographic process in which surface water pushed offshore by winds is replaced by cold, nutrient-rich water from depth, appears to cause variation in rocky intertidal communities. Along the central Oregon coast upwelling occurs intermittently during the summer while on the southern coast it begins earlier in the spring a...

The Belgian Coastal Zone (BCZ) in the Southern Bight of the North Sea is a highly dynamic and optically complex area. This is due to high non-algal particles (NAP) and coloured dissolved organic matter (CDOM) content which in spring adds together with undesirable blooms of the haptophyte Phaeocystis globosa. There is a need for improving the algorithms for chlorophyll a (chl a) retrieval in these highly turbid waters and for developing algorithms for species detection in order to attempt to crea...

Prediction equations were developed for estimating the flow regime at ungaged stream locations in the Oregon coastal range. Principal components analysis was used to screen the initial data set of physiographic and meteorological parameters. The final regression equations for predicting mean monthly flow had standard errors of estimate ranging from 3 to 42 percent, with an average standard error of 13.5 percent. A linear prediction equation was found to give the best results for drainage basins ...

<p>Utvecklingen av algblomningar i Östersjön har blivit mer diskuterat i media under senare år. Eftersom algblomningar ofta infaller samtidigt som turistsäsongen så har områden som är beroende av turistnäringen drabbats hårt. Under sommaren 2005 inträffade massiva giftiga algblomningar i Östersjön, och detta påverkade turismen på Öland negativt ur ekonomisk synpunkt. Mänsklig påverkan är ansedd vara huvudorsaken bakom den ökade förekomsten av algblomningar i Östersjön. Målet med detta projekt är...

<p>The condition of the herring (<em>Clupea harengus</em>) in the Baltic Sea has decreased during the past 30-40 years. This decrease could be explained by different factors; (1) change in diet due to changes in zooplankton community, (2) changes in water temperature and salinity, (3) increasing nutrient inputs and (4) competition for food with other species such as sprat (<em>Sprattus sprattus</em>). In this study the change in condition was analysed using the Fulton’s condition index, and by l...

Through international agencies and non-governmental organisations building their work on the United Nations Convention on the Rights of the Child, childhood has become increasingly homogenised as an idea. A ‘global model’ of childhood is promoted all over the world, but this is a model who fails in recognising the diverse realities of children’s lives. The diversity of childhood is on the other hand demonstrated through a growing body of literature on local childhood experiences, also in the maj...

A multiple-proxy study for borehole sediments from the Bengal Basin reveals stratigraphic, paleoenvironmental, and provenance data which suggest repeated event deposition, river avulsion and abandonment, and shifting provenance sources to the Ganges-Brahmaputra (G-B) margin during Late Quaternary delta evolution. Results indicate that the G-B delta system is not simply an amalgam of homogenous sediments, but, rather, is comprised of stacked units with distinct lithologies deposited from at least...

Coastal storm surges from hurricanes are one of the most costly natural disasters in the United States (US). Current research arguably indicates a mean sea-level (MSL) increase due to global warming, as well as an increase in damages caused by hurricanes under climate change. The objectives of this research are: 1) to develop a framework that integrates Geographical Information Systems (GIS) with hurricane storm surge numerical models; 2) to quantify the uncertainty derived from coastal land cov...

Eutrophication, particularly due to nitrogen (N) and phosphorus (P) input, has been massively altered by anthropogenic activities. Thus it is important to understand the impact on salt marsh plants; however studies on salt marsh plants within Galveston Bay, Texas are limited. In this study, the effects of repeated nutrient additions in monospecific plots of Spartina alterniflora, Batis maritima¸ and Salicornia virginica as well as mixed plots of B. maritima and S. virginica were studied over 15 ...
