Examining Dissolved Gases In A Changing Climate, Allison Staniec
Examining Dissolved Gases In A Changing Climate, Allison Staniec
Doctoral Dissertations
Changing climate scenarios predict a variety of effects across land, ocean, and atmosphere. In this dissertation the effect of several climate change related phenomena on dissolved gases in the coastal ocean and across the ocean-atmosphere interface is examined. Warming temperature, as predicted by the IPCC (2014), has direct impacts on the capacity of water to act as a reservoir for dissolved gases through its effect on their solubility (Chang, 2010). The first portion of this dissertation addresses dissolved gases in a coastal estuary, where warming is expected to be accelerated relative to the open ocean. A representative gas, oxygen, is …
A Regional Vulnerability Assessment For The Dungeness Crab (Metacarcinus Magister) To Changing Ocean Conditions: Insights From Model Projections And Empirical Experiments, Halle Berger
Master's Theses
Among global coastal regions, the Northern California Current System (N-CCS) is already experiencing effects from ocean acidification and hypoxia during the summer, primarily due to the region’s seasonal upwelling, current systems, and high productivity. Oxygen, pH, and temperature conditions are expected to become more stressful with continued fossil fuel emissions under global climate change, posing a serious threat to the region’s fisheries. N-CCS fishing communities rely heavily on the economically and culturally important Dungeness crab (Metacarcinus magister). The fishery is currently sustainably managed, but potential negative impacts from changing ocean conditions on Dungeness crab life stages and populations …
Fine-Scale Climates And Evolution Alter Species Responses To Climate Change, Christopher Nadeau
Fine-Scale Climates And Evolution Alter Species Responses To Climate Change, Christopher Nadeau
Doctoral Dissertations
Predictions suggest that climate change could cause the extinction of up to a million species. However, scientists debate the accuracy of these predictions. In this dissertation, I explore whether often-ignored aspects of climate and biology alter predictions of climate change impacts. In Chapter 1, I show that studies predicting extinction risk under climate change ignore important aspects of climate by using climate data with coarse spatial and temporal resolutions. In Chapter 2, I propose that the degree to which climates vary over space and time in a region can predict the vulnerability of species to climate change. I suggest that …
