The Nexus of Oceans and Human Health
This talk will outline the beginning and scope of the meta‐discipline of Oceans and Human Health (OHH), which includes risks and benefits from the sea. The talk will center on the history and activities within the Woods Hole Center for Oceans and Human Health. Pressure from the scientific community led to an unprecedented agreement between the National Science Foundation and the National Institute of Environmental Health Sciences, part of the NIH, to jointly fund a new program to establish Centers for Oceans and Human Health. The Woods Hole COHH was one of four centers established in 2004 and has been successful in repeated funding competition for the past 20 years, and now has renewed funding for the next five years. The focus of the Woods Hole COHH has been primarily on understanding and predicting harmful algal blooms, the mechanisms of toxin effect on nervous system development, as well as communication with a broad range of stakeholders. These activities are embedded in a broader array of research in the village, at WHOI and MBL, that collectively address the scope of OHH as envisioned. The topic addressed is pertinent to current strategic planning.

Physiological and EcologicalConsequences of High Hydrostatic Pressure for Deep-Sea Fishes
The deep ocean represents the largest habitable environment on our planet. Although humans typically consider deep-sea environments harsh—with cold temperatures, high pressures, an absence of sunlight, and an often-limited food supply—these habitats are home to an amazing diversity of fishes. This talk explores how environmental conditions in the deep ocean structure the distribution and adaptations of bony fishes, with a focus on hydrostatic pressure. First, we investigate how deep-sea fishes show specialized adaptation to hydrostatic pressure by accumulating the pressure-counteractant trimethylamine n-oxide and intrinsically changing enzyme structure to function at depth. We illustrate how the limits of these molecular adaptations likely limit fishes from inhabiting full-ocean depths. Second, we discuss how high hydrostatic pressures influence buoyancy in deep-living fishes, with implications for the evolution of fish skeletons. Finally, we examine how deep-sea conditions have influenced the morphology and function of fish otoliths and patterns of longevity with increasing habitat depth. This research applies an integrative approach, spanning molecular, organismal, and ecological scales to inform new understanding of life in the deep ocean and the evolutionary consequences of high hydrostatic pressures.
