• The relationship between current flow direction and sediment distribution within slope-confined submarine canyons off the north coast of Moloka’i, HI 

  Maran, Heather (2023-06)

  Submarine canyons play an important role in transporting sediments from terrestrial sources to abyssal environments. Sediment can be transported along continental shelves and into submarine canyons through bottom currents ...

• Changes in bacterial concentrations with depth, temperature, and chlorophyll fluorescence in the Equatorial Pacific Ocean 

  Lim, Eunie (2023-06)

  It is important to consider the abundance of marine bacteria, as they play important roles in biogeochemical processes that are significant in the carbon cycle. Marine bacteria can give us insight about factors such as the ...

• The effects of nutrient additions to phytoplankton size structures based on chlorophyll in the Equatorial Pacific Ocean 

  Johnson, Connor (2023-06)

  Phytoplankton, the primary producers of ocean, have produced over half of the oxygen in the atmosphere and use dissolved carbon dioxide to accumulate biomass which is critical to the biological pump. In High-Nutrient, ...

• Measuring the abundance and distribution of microplastics and marine organisms across the surface of the equatorial Pacific using a Manta Net 

  Gala, Isabel (2023-06)

  The increasing production of plastics and their long lifespan have led to concerns about the accumulation of microplastics in marine environments. Due to their ability to be mistaken for food, microplastics act as a ...

• Interpretation of a temperature and salinity section at 180 degrees longitude in relation to the ENSO cycle in the equatorial Pacific for March 2023 

  Zhao, Elliot (2023-06)

  El Niño-Southern Oscillation (ENSO), which is the cycle consisting of El Niño and La Niña has major global impacts on climate. El Niño and La Niña are characterized by large changes in temperature in the equatorial ...

• Natural and Anthropogenic Changes to the Dissolved Inorganic Carbon System in the Western Equatorial Pacific During the Last Three Decades 

  Dominguez-Giron, Tony (2023-06)

  The Western Pacific is a relatively unstudied area that is important for the climate because it is influenced not only by natural processes such as El Niño Southern Oscillation (ENSO) and seasonal variability but also the ...

• Evolution of submarine terraces off Northern Moloka’i, HI 

  Baker, Autumn (2023-06)

  Submarine terraces off Northern Moloka’i, HI, have been understudied. Terraces are vital to our understanding of sea-level changes and terrestrial alterations. One study aimed to identify terraces and evaluate their ...

• Determining CO2 Balance influenced by Upwelling and Primary Production in the Equatorial Pacific Region at 180° using CO2 and O2 flux 

  Ahuja, Amrita (2023-06)

  The oceanic carbon cycle is one of the most important mechanisms in controlling the Earth’s climate as oceans take up to 30% of the carbon emissions, acting as a major sink. The ocean’s biological and solubility pumps are ...

• Implications of Bald Eagle (Haliaeetus leucocephalus) Predation on the Goose Island Glaucous-winged Gull (Larus glaucescens) Nesting Colony 

  Combs, Leilani; Dingel, Hannah; Hessen, Nora (2023)

  In Washington state, rebounding Bald Eagle (Haliaeetus leucocephalus) populations are having both direct and indirect effects on the reproductive success of seabirds like Glaucous-winged Gulls (Larus glaucescens). In an ...
