Data & Publications

An unprecedented coastwide toxic algal bloom linked to anomalous ocean conditions

A coastwide bloom of the toxigenic diatom Pseudo-nitzschia in spring 2015 resulted in the largest recorded outbreak of the neurotoxin, domoic acid, along the North American west coast. Elevated toxins were measured in numerous stranded marine mammals and resulted in ...

Analyses of the complete chloroplast genome sequences of two members of the Pelagophyceae: Aureococcus anophagefferens CCMP1984 and Aureoumbra lagunensis CCMP1507

Heterokont members of the Pelagophyceae form the massive brown tides that have continually plagued the coastal regions of the eastern U.S. seaboard and the Gulf of Mexico. To gain a better understanding of the photosynthetic competence that may be linked ...

Aquatic invasive species transport via trailered boats: what is being moved, who is moving it, and what can be done?

Trailered boats have been implicated in the spread of aquatic invasive species. There has been, however, little empirical research on the type and quantity of aquatic invasive species being transported, nor on the efficacy of management interventions (e.g., inspection crews, ...

Assessing biophysical controls on Gulf of Mexico hypoxia through probabilistic modeling

A mechanistic model was developed to predict midsummer bottom-water dissolved oxygen (BWDO) concentration and hypoxic area on the Louisiana shelf of the northern Gulf of Mexico, USA (1985–2011). Because of its parsimonious formulation, the model possesses many of the benefits ...

Assessment of hypoxia-inducible factor-1α mRNA expression in mantis shrimp as a biomarker of environmental hypoxia exposure

Efforts to assess the ecological impacts of the marked increase in coastal hypoxia worldwide have been hampered by a lack of biomarkers of hypoxia exposure in marine benthic organisms. Here, we show that hypoxia-inducible factor-1α (HIF-1α) transcript levels in the ...
