Establishing interest in and understanding of the marine environment : an educational and cooperative approach utilizing an open source CTD

Creator:: Black, Ian
Abstract:: A number of groups in the United States have expressed concern regarding the state of public ocean literacy and the capabilities of the future marine STEM workforce. This pilot study explores some of the requirements for workforce development and the expansion of ocean literacy by introduction of fundamental ocean properties...

Stratigraphic correlation of seismoturbidites and the integration of sediment cores with 3.5 kHz chirp subbottom data in southern Cascadia

Creator:: Black, Bran
Abstract:: In order to evaluate the shallow stratigraphy along the southern Cascadia abyssal margin and northern California abyssal plain, CHIRP subbottom profiles capable of imaging individual turbidite beds in the upper tens of meters of the subsurface were collected. Reflectors imaged with the 3.5 kHz CHIRP subbottom data represent turbidite beds...

Unraveling the Diagenetic Cycling and Sequestration of Rare Earth Elements (REEs) in Marine Sediments to Understand REE Accumulation in Ancient Shales

Creator:: Yang, Jon
Abstract:: The rare earth elements (REEs) have been established as powerful tracers for a range of physiochemical processes occurring in the natural environment. They also hold significant economic importance as many technological advancements are reliant upon the REEs for their unique magnetic, luminescent, and electrochemical characteristics. In sedimentary settings, understanding the...

Hydrogen isotopic composition of C₃₇ alkenones and the ecology and physiology of coccolithophores

Creator:: Wolhowe, Matthew D.
Abstract:: A three-part study was conducted into the impact of physiological and ecological variables on the net isotopic fractionation of hydrogen, α[subscript K₃₇], expressed in C₃₇ alkenones. First, alkenone-producer production, abundance, and export were characterized in the summertime Gulf of California and Eastern Tropical North Pacific using compound-specific, labeled in situ...

Impact of tide-topography interactions on basal melting of Larsen C Ice Shelf, Antarctica

Creator:: Mueller, R. D., Padman, L., Dinniman, M. S., Erofeeva, S. Y., Fricker, H. A., and King, M. A.
Abstract:: Basal melting of ice shelves around Antarctica contributes to formation of Antarctic Bottom Water and can affect global sea level by altering the offshore flow of grounded ice streams and glaciers. Tides influence ice shelf basal melt rate (w(b)) by contributing to ocean mixing and mean circulation as well as...

Resurgent Uplift of Samosir Island in Toba Caldera, Indonesia : Insights from Lake Sediment Paleomagnetism and C-14 Age Determination

Creator:: Solada, Katharine
Abstract:: Around 74 ka, a supervolcano, Toba Caldera in Sumatra, Indonesia erupted, producing the Youngest Toba Tuff and its associated caldera. After this catastrophic eruption, a lake filled the caldera, sedimentation within the lake occurred, and the process known as resurgence began. Today, the resurgent dome, Samosir Island, is uplifted 700...

Coupling of Boundary Layer Dynamics, Turbulence, and Moisture Transport to Cloud Characteristics and Aerosol Concentrations

Creator:: Henze, Dean C.
Abstract:: Uncertainties in general circulation model (GCM) representations of marine boundary layer (MBL) shallow cloud cover contribute substantially to the spread in model predictions of future climate. Further uncertainties in GCM output arise from an incomplete understanding of cloud-aerosol interactions. For example, the Fifth Assessment Report from the Intergovernmental Panel on...

Abrupt deglacial climate changes in the North Pacific and implications for climate tipping points

Creator:: Praetorius, Summer Kate
Abstract:: Paleoclimate archives have revealed abrupt climate events that are superimposed on more gradual climate changes throughout the last glacial and deglacial periods. The underlying causes of such rapid climate changes are still poorly understood, but the strong expression of these events in northern hemisphere records likely points to climatic mechanisms...

What's that on the beach? Designing a Protocol for the Identification and Reporting of Stranded Marine Fish, Squid, and Turtles Using the Oregon Coast as a Proof-of-Concept

Creator:: Asson, Danielle and Asson, Danielle C.
Abstract:: It is not unusual to see stranded or washed-up marine animals and birds along any coastline. Various networks nationwide exist to report marine mammals and sea birds, yet, we have been unable to find a network in Oregon or nationally to report other stranded marine animals, namely fish, cephalopods, and...

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...
