2009, Conference Paper, Estuarine and coastal modeling : proceedings of the eleventh international conference, November 4-6, 2009, Seattle, Washington
Habitat in open water is not simply a 2-D to 2.5-D surface such as the ocean bottom or the air-water interface. Rather, pelagic habitat is a 3-D volume of water that can change over time, leading us to the term habitat space. Visualization and analysis in 2-D is well supported...
Earth science: lasting earthquake legacy
Thomas E. Parsons
2009, Nature (462) 41-42
Earthquakes occur within continental tectonic plates as well as at plate boundaries. Do clusters of such mid-plate events constitute zones of continuing hazard, or are they aftershocks of long-past earthquakes? Early on the morning of 16 December 1811, an earthquake of about magnitude 7 shook the centre of the United States...

Reassessment of the predatory effects of rainbow smelt on ciscoes in Lake Superior
Jared T. Myers, Michael L. Jones, Jason D. Stockwell, Daniel L. Yule
2009, Transactions of the American Fisheries Society (138) 1352-1368
Evidence from small lakes suggests that predation on larval ciscoes Coregonus artedi by nonnative rainbow smelt Osmerus mordax can lead to cisco suppression or extirpation. However, evidence from larger lakes has led to equivocal conclusions. In this study, we examine the potential predation effects of rainbow smelt in two adjacent but contrasting embayments in...
