The Effects of Ocean Freshening on Marine and Atmospheric Circulation: Impacts and Solutions

Ocean freshening (the desalination of the oceans) is occurring, in part, due to increased terrestrial runoff and ice cap melting caused by rising carbon dioxide emissions. Ocean freshening causes a variety of problems on its own, independent of other variables of global climate change.

The Effects of Declining Sea Ice on Narwhals

Narwhal populations number around 80,000 individuals (Laidre, n.d.). Threats to narwhals include polar bears, orca whales, and entrapments in sea ice (“The Narwhal’s Tale: Surviving Sea Ice Change,” 2012). Other potential problems include the melting of global sea ice, which will reshape their habitat.

Decreasing Arctic Sea Ice Through the Eyes of Spectacled Eiders

Arctic sea ice is decreasing due to carbon emissions and greenhouse gases, with rates of decline between 2001-2005 at 8.6%. Ice Mass Buoys have been used to gather data suggesting that the sea ice thickness is decreasing twice as fast as sea ice extent is. Models predict that sea ice is ever declining though rates vary model to model.

Tsunami and Earthquake Effects and Coastal Resilience in Palmer, Alaska

We of the Palmer High Ocean Bowl team based our research project on the concept that the Matanuska-Susitna Valley could be washed out by a tsunami of a significant size. We chose this topic because our team members are residents of the valley and wanted to investigate the effects of a tsunami on the local area and what could be done to protect our home and keep it resilient.

The Impact of Tributyltin in the Cook Inlet Watershed

From the shores of England to the watersheds of Alaska, all marine environments face degradation with the exposure of tributyltin, commonly known as TBT. Since the introduction of TBT in the 1960s, boat hulls and fishing equipment have become more hydrodynamic by eliminating microbial organisms’ growth on marine equipment therefore increasing efficiency.

The Effects of Erosion and Sea Level Rise on the Coastal Villages of Newtok and Kivalina

Coastal resilience is the ability in which a city is able to come back from a disaster, and not just react to the threat. The threat we are researching is sea level rise in conjunction with erosion of the coast. Both Kivalina and Newtok are estimated to go under water within ten years, and not much can be done to stop the rising tides of water engulfing the land around these cities.

Ringed Seal (Phoca hispida) And The Shrinking Arctic Sea Ice

It is now a common belief that global warming is the main cause for the melting of the sea ice of our planet Earth. The Arctic Sea ice is no exception. Evidences of scientific exploration and research with the aid of satellite technology reveal that the Arctic sea ice is continuously shrinking.

Garbage Patches Threaten Oceanic Life

A “plastic soup” of waste floating in the Pacific Ocean is growing at an alarming rate and now covers an area twice the size of the continental United States. In 1997, the oceanographer Charles Moore discovered this garbage patch. Ninety percent of these sea wastes are plastics. This study focuses on the impact of plastics to marine life and specifically to the albatross colony of Alaska.

Characterization of the Purity of Curcumin Extraction: Comparative study of UV Spectrophotometry and High Performance Liquid Chromatography from a Field Application Perspective

This study focuses on the comparison of UV Spectrophotometry and High Performance Liquid Chromatography (HPLC) for characterizing purity of curcumin with the view of selecting the best technique for this particular commercial application. Field application was a key criterion in the selection.

Sea Cucumber Ecosystem Based Management Plan

Dive fisheries in Southern Southeast Alaska are important to the local area and have a significant impact that some people aren’t very aware of. With the increasing use of sea cucumbers in the past few years, it is important that there are plans to keep the populations up without harming or affecting the environment in a negative way.
