This tabular dataset is the result of field sampling of coral tissues (Pocillopora damicornis) and subsequent laboratory chemical analysis for pollutant levels. The pollutants analyzed included trace elements (Al, Ar, Cd, Cr, Cu, Fe, Pb, Mn, Hg, Ni, Se, Ag, Sn, Zn), PAHs, PCBs, pesticides (chlordanes, DDT, HCH), and organotins ...

Kachemak Bay, in Cook Inlet Alaska, is a rich, diverse marine ecosystem and contains all of the estuarine and coastal habitat types found in the Gulf of Alaska. However, the bay has experienced significant long-term and recent environmental and ecological changes. Our ecological assessment and related products brings together diverse ...

In 2004, shallow-water benthic habitats were mapped in Saipan Lagoon, Commonwealth of the Northern Mariana Islands. Since then, habitats in the lagoon have likely changed because of coral bleaching events and recent typhoons. Local resource managers requested an updated map to help better understand these habitat changes and to help ...

Riprap-reinforced shorelines are becoming more prevalent as a result of increasing coastal development and sea level rise. Altered morphology at the land-water interface, associated with riprap shorelines, has the potential to reduce shore-zone habitat quality for associated nekton species. The shore-zone nekton assemblage within a temperate, mid-Atlantic coast, USA, estuary ...

The cumacean fauna of the Caribbean mesophotic reefs is remarkably rich but understudied. Herein, we present the description of 22 new species of the family Nannastacidae, including one from shallow reefs, 20 of them belonging to Cumella (Cumella) and two new species belonging to the subgenus Cumewingia. We have also ...

Pulley Ridge, a limestone ridge that extends nearly 300 km along the southwestern Florida shelf in the eastern Gulf of Mexico, supports a mesophotic coral ecosystem (59 to 94 m deep), surrounded by deeper waters. An ongoing evaluation of Porifera biodiversity observed and collected during expeditions by Harbor Branch Oceanographic ...

Herein, we present the description of 22 new species of the family Nannastacidae, including one from shallow reefs, 20 of them belonging to Cumella (Cumella) and two new species belonging to the subgenus Cumewingia.

Ulvalean algae (Chlorophyta) are most commonly described from intertidal and shallow subtidal marine environments worldwide, but are less well known from mesophotic environments. Their morphological simplicity and phenotypic plasticity make accurate species determinations difficult, even at the generic level. Here, we describe the mesophotic Ulvales species composition from 13 locations ...

Harmful algal blooms (HABs) cause significant economic and ecological damage worldwide. Despite considerable efforts, a comprehensive understanding of the factors that promote these blooms has been lacking, because the biochemical pathways that facilitate their dominance relative to other phytoplankton within specific environments have not been identified. Here, biogeochemical measurements showed ...

Diarrhetic Shellfish Poisoning (DSP) is a globally significant human health syndrome most commonly caused by dinoflagellates within the genus Dinophysis. While blooms of harmful algae have frequently been linked to excessive nutrient loading, Dinophysis is a mixotrophic alga whose growth is typically associated with prey availability. Consequently, field studies of ...

The National Oceanic and Atmospheric Administration (NOAA) Deep-Sea Coral Research and Technology Program (DSCRTP) was launched in 2009, following the reauthorization of the Magnuson-Stevens Fishery Conservation and Management Act (MSA). The goal is to provide scientific information needed to conserve and manage deep-sea coral ecosystems in the United States (NOAA ...

Spatial information about the seafloor is critical for decision-making by marine resource science, management and tribal organizations. Coordinating data needs can help organizations leverage collective resources to meet shared goals. To help enable this coordination, the National Oceanic and Atmospheric Administration (NOAA) National Centers for Coastal Ocean Science (NCCOS) developed ...

The presence of Vibrio vulnificus (Vv), a naturally-occurring bacteria that can be harmful to human health, is related to temperature and salinity. Vv forecasts for the Chesapeake Bay based on Operational Forecast Systems (CBOFS) include daily and next day probability forecast guidance on the CBOFS model grid. The occurrence of ...

This dataset includes outputs from an ecosystem model, which is a tool for regional science managers to explore marine spatial planning scenarios in the context of static and dynamic environmental covariates. The dataset includes predicted fish biomass from the Ecopath with Ecosim and Ecospace model set up over the Florida ...

The North Carolina Sentinel Site Cooperative (NCSSC) was established in 2012 as part of a National Oceanic and Atmospheric Administration (NOAA) effort to provide coastal communities and resource managers with information on the potential impacts of sea level rise on coastal habitats. The NCSSC utilizes a collaborative business model to bring together stakeholders, including ...

The Louisiana shelf, in the northern Gulf of Mexico, receives large amounts of freshwater and nutrients from the Mississippi–Atchafalaya river system. These river inputs contribute to widespread bottom-water hypoxia every summer. In this study, we use a physical–biogeochemical model that explicitly simulates oxygen sources and sinks on the Louisiana shelf ...

Numerical models can provide the needed information for understanding hypoxia and ensuring effective management, and this book provides a snapshot of representative modeling analyses of hypoxia and its effects. In this chapter, we used the modeling and analyses across the other 14 chapters to illustrate 8 themes that relate to ...

Multi-year nitrogen (N) and phosphorus (P) budgets were developed for the Patuxent River estuary, a seasonally stratified and moderately eutrophic tributary of Chesapeake Bay. Major inputs (point, diffuse, septic, and direct atmospheric) were measured for 13 years during which, large reductions in P and then lesser reductions in N-loading occurred ...

The continental shelf adjacent to the Mississippi River is a highly productive system, often referred to as the fertile fisheries crescent. This productivity is attributed to the effects of the river, especially nutrient delivery. In the later decades of the 20th century, though, changes in the system were becoming evident ...

Long?SAGE (serial analysis of gene expression) was used to profile the transcriptome of the brown tide?forming alga, Aureococcus anophagefferens, under nutrient replete (control), and nitrogen (N) and phosphorus (P) deficiency to understand how this organism responds at the transcriptional level to varying nutrient conditions. This approach has aided A. anophagefferens ...
