Both physical oceanographic processes and marine geological features in the continental shelf can cause the medium properties to have lateral heterogeneity, so horizontal refraction of sound can occur and produce significant three-dimensional (3-D) sound propagation effects. The long-term goals of this project are targeted on understanding the 3-D acoustic effects caused by the environmental fa...

ULow-frequency ambient noise under pack ice of the central Arctic Ocean has long-term variations mmj (periods greater than I h) which correlate highly with composit -measures of stress applied to the mice by wind, current, and drift. These composites are the horizontal ice stress and the stress moment, and are derived from meteorological and oceanographic data observed simultaneously with the n...

Climate change is perhaps the most pressing and urgent environmental issue facing the world today. However our ability to predict and quantify the consequences of this change is severely limited by the paucity of in situ oceanographic measurements. Marine animals equipped with sophisticated oceanographic data loggers to study their behavior offer one solution to this problem because marine anim...

The status of the NEMO project is described: the activity on long term characterization of water optical and oceanographic parameters of the Capo Passero (Sicily, Italy), candidate for the installation of the Mediterranean km neutrino telescope; the feasibility study on physics performances and underwater technology for the km; the activity on NEMO Phase 1, a technological demonstrator that is ...

Underwater sound propagation in the continental shelf is complicated due to many threedimensional (3-D) oceanographic and marine geologic features, such as shelfbreak fronts, nonlinear internal gravity waves and topographic variability. The long-term goals of this project are targeted on understanding the 3-D sound propagation effects caused by these environmental factors, and also on applying ...

[1] Chemical analysis of deepwater octocorals collected at 1000 m depth off southern Australia indicates long-term cooling, beginning in the mid-18th century. This cooling appears to reflect shoaling of isotherms along the continental shelf, that can be related statistically, observationally and by modeling to increasing coastal seasurface temperatures, that in turn reflect a poleward extension...

The U.S. Pacific Islands span a dramatic natural gradient in climate and oceanographic conditions, benthic community states vary significantly across the region’s coral reefs. Here we leverage decade of integrated ecosystem monitoring data from American Samoa, Mariana Archipelago, main Northwestern Hawaiian Islands, Remote Island Areas to evaluate reef structure processes strong pH aragonite sa...
