Macrobenthic polychaetes play a significant role in marine benthic food chain. A study was carried out to observe the abundance and diversity of soft bottom macrobenthic polychaetes along the South Indian coast, along with observations on sediment characteristics. The present study indicated an increase in the polychaete diversity as compared to earlier reports. Sixty-three different forms of p...

Kinematic data from two segments of the Coast Range fault are used to test the hypothesis that the Franciscan subduction complex was exhumed by extensional faulting. The data reveal a consistent geometry for the principal directions of brittle strain. The maximum extension direction has an east-west orientation and lies subperpendicular to the present attitude of the Coast Range fault, which di...

In this paper, we present our collaborative work with the U.S. Coast Guard’s Ninth District and Atlantic Area Commands where we developed a visual analytics system to analyze historic response operations and assess the potential risks in the maritime environment associated with the hypothetical allocation of Coast Guard resources. The system includes linked views and interactive displays that e...

The Northwest Coast stretches 1,800 km from Cape Mendocino, California, to Yakutat Bay, Alaska. It is usually divided into three or four subregions (Fig. 1), with the Oregon and northern California coasts the most ambiguous in their assignment to the Northwest Coast. In the nineteenth century, this was linguistically one of the most diverse regions of North America, with eight language families...

The US Pacific Coast has been largely free of fishery collapses that have occurred elsewhere, but the situation appears to be changing. Here, we show results from the first systematic study of demersal fishes along the US Pacific Coast. Using data from a quarter-century long, fishery-independent, coast-wide trawl survey, we document fundamental shifts in the demersal fish assemblage along the U...
