A Model Study Of The Copper River Plume And Its Effects On The Northern Gulf Of Alaska, Yuan Wang
A Model Study Of The Copper River Plume And Its Effects On The Northern Gulf Of Alaska, Yuan Wang
Electronic Theses and Dissertations
Using a three-level nested Regional Ocean Modeling System coupled with the Carbon, Silicate, Nitrogen Ecosystem model, this study examined the seasonal evolution of the Copper River (CR) plume and how it influences the along- and across-shore transport in the northern Gulf of Alaska (NGoA). A passive tracer was introduced in the model to delineate the growth and decay of the plume and to diagnose the spread of the CR discharge in the shelf, into Prince William Sound (PWS) and offshore. Furthermore, a model experiment with doubled discharge was conducted to investigate potential impacts of accelerated glacier melt in future climate …
Developing An Acoustic Method For Reducing North Atlantic Right Whale (Eubalaena Glacialis) Ship Strike Mortality Along The United States Eastern Seaboard, Kaitlyn Allen Mullen
Developing An Acoustic Method For Reducing North Atlantic Right Whale (Eubalaena Glacialis) Ship Strike Mortality Along The United States Eastern Seaboard, Kaitlyn Allen Mullen
Electronic Theses and Dissertations
North Atlantic right whales (Eubalaena glacialis) are among the world’s most endangered cetaceans. Although protected from commercial whaling since 1949, North Atlantic right whales exhibit little to no population growth. Ship strike mortality is the leading known cause of North Atlantic right whale mortality. North Atlantic right whales exhibit developed auditory systems, and vocalize in the frequency range that dominates ship acoustic signatures. With no behavioral audiogram published, current literature assumes these whales should be able to acoustically detect signals in the same frequencies they vocalize. Recorded ship acoustic signatures occur at intensities that are similar or higher to those …
Holocene Glacial History Of Renland, East Greenland Reconstructed From Lake Sediments, Aaron Medford
Holocene Glacial History Of Renland, East Greenland Reconstructed From Lake Sediments, Aaron Medford
Electronic Theses and Dissertations
The Arctic is responding to the modern increase in temperature, resulting in ice loss and consequent sea-level rise. In order to understand present-day changes, we need to understand how the Arctic has reacted in the past to natural variations in climate forcing. To begin to identify the mechanisms behind climate change, I produced a Holocene glacial and climate record for the Renland Ice Cap, Scoresby Sund, East Greenland, from sediments in glacially fed lakes. I cored Rapids and Bunny Lakes, which are fed by meltwater from the Renland Ice Cap, as well as Raven Lake, which does not receive glacial …
