Atmospheric and Sea Ice Circulation Patterns During Lead Formation at Point Barrow

Creator:: Jewell, MacKenzie E.
Abstract:: In winter and spring, ice-coast interactions driven by winds and ocean currents cause sea ice fractures (leads) to form repeatedly along Arctic coastlines. These events are often associated with rapid and expansive changes in sea ice drift and state that are challenging to predict and represent in models. We investigate...

Oceanographic Drivers of Northern California Current Phytoplankton Communities and their Fatty Acid Composition: Implications for Northwest Fisheries

Creator:: Smoak, Rebecca T.
Abstract:: Micro-plankton are a crucial component of pelagic food webs, responding rapidly to environmental changes, and providing a first step in the acquisition and transfer of nutrients to life in the ocean. In addition to the uptake of carbon, phytoplankton provide essential fatty acids (FAs) that can limit the growth of...

The 3.1 Ma to 100 ka Goat Rocks Volcanic Complex: Persistence and Evolution of Magmatism at a Long-Lived Major Andesite Locus on the Cascade Arc

Creator:: Wall, Kellie T.
Abstract:: The imposing andesite stratovolcano is the characteristic expression of subduction zone magmatism, posing hazards to coastal populations and bearing insight into deep Earth processes. On a map of a typical volcanic arc, one can easily distinguish the approximately linear alignment and regular spacing of these major edifices that stand out...

Concentration-Runoff Relationships of Contrasting Small Mountainous Rivers in the Pacific Northwest, USA: Insights into the Weathering of Rhenium

Creator:: Ghazi, Layla
Abstract:: This study examines dissolved rhenium (Re) as a function of water runoff using river samples from two contrasting watersheds, the Eel and Umpqua Rivers in the Pacific Northwest, USA. These watersheds share many key characteristics in terms of size, discharge, climate, and vegetation, but they have a 10-fold difference in...

Role of Sea Surface Physical Processes in Mixed-layer Temperature Changes During Summer Marine Heat Waves in the Chile-Peru Current System

Creator:: Cooley, Kylene M.
Abstract:: Development of marine heat waves (MHWs) in the Chile-Peru Current System (CPCS) is influenced by multiple physical processes at the air-sea interface whose individual role in these destructive events is difficult to infer. We identified MHW events from sea surface temperature (SST) anomalies from time periods of extreme ocean warming...

A Multivariate Analysis of Pacific Arctic Surface Waters

Creator:: Bryant, Aleesa
Abstract:: The Pacific Arctic is undergoing rapid biogeochemical changes in response to warming air temperatures caused by climate forcing. This is manifesting as changes in seasonal sea ice thickness and sea ice extent, as well as changes in primary production within surface waters. The data and samples analyzed here were collected...

Incorporating the Impacts of Climate Variability on Growth in Fish Population Dynamics Models

Creator:: Moron Correa, Giancarlo Helar
Abstract:: Variations in ocean conditions influenced by climate fluctuations may impact fish populations by changing their spatial distribution, physiology, survival, and other ecological features. Somatic growth is a crucial aspect of the biology of fishes and an important contributor to biomass fluctuations. Climate variability also affects somatic growth rates along the...

Buffering Estuarine Sediments Against Acidification

Creator:: Myers, Tristen J.
Abstract:: Globally rising anthropogenic CO₂ emissions have resulted in the increased prevalence of ocean acidification (OA) which has the potential to impact shell-forming organisms. On geologic timescales, the largest contributor to atmospheric CO₂ was volcanoes, counterbalanced by weathering and erosion, but due to increased anthropogenic emissions, these processes alone can no...

Investigating Influences of Natural and Anthropogenic Lead Sources on Environmental Archives at Multiple Spatial and Temporal Scales: Evidence from Oysters and Ice Cores

Creator:: Wensman, Sophia M.
Abstract:: Environmental archives provide records of natural and anthropogenic variation in the environment at different temporal and spatial scales. Lead (Pb) concentrations and isotopic ratios are useful tracers of anthropogenic emissions from industrial activities including mining, smelting, and leaded gasoline use, however, methods of measuring Pb are largely limited in low...

Evaluating Spatial Patterns of Heavy Metal Levels and Pb Isotopic Compositions of Peat Soils along the Red Dog Mine Haul Road in Northwest Alaska

Creator:: Melby, Kali M.
Abstract:: This study evaluates ore transport and other mining activities on metal levels in the remote Arctic ecosystem of Cape Krusenstern National Monument (CAKR) in northwestern Alaska. This monument is 50 km SW of Red Dog Mine, one of the world’s largest Pb–Zn mines. The Delong Mountain Transportation System (DMTS) haul...
