This paper describes an integrated sensor system for precision maritime surface navigation in tightly confined harbor environments. The system tightly integrates GPS, inertial, image and laser measurements with an onboard electronic charting system to provide accurate bearing and/or range measurements to known navigational aids, allowing robust and accurate piloting relative to navigation aids ...

REPRESENTATIVE FANNING ISLAND INSHORE FISHES were collected by means of rotenone poisoning in January 1970. The collections were made with the objective of elucidating the zoogeographic relationships of the Line Islands fish fauna. The results are presented here. Zoogeographically, the Central Pacific forms an eastward extension of the great Indo-West Pacific faunal region centered today in the...

Arctic Terns Sterna paradisaea have the longest known migration of any bird species, from the Arctic to the Antarctic, covering up to 80 000 km during a round trip (Egevang et al. 2010). We report here on an apparent trans-Andean passage by southward migrating Arctic Terns on a route that takes them from the rich inshore upwellings of southwestern South America, over the Andes, to the highly pr...

Some of the inshore reefs of the Great Barrier Reef are showing impacts consistent with a decline in water quality as a result of increased sediments and nutrients. The Wet Tropics covers approximately 2.2 million hectares and includes 91 percent of the Wet Tropics World Heritage area. The climate and geomorphologic conditions of the region are unique in Australia and generally result in fast f...

In the absence of reliable survey data, habitat modelling can direct conservation and fishery management efforts. We have constructed a model designed to predict high-value inshore rockfish habitat, based on the variables of topographical complexity and kelp density. When applied in our pilot study area, this model showed remarkable accuracy at predicting areas previously identified by commerci...
