Provenance Tracing Of Glacial Sediment From The Foundation, Academy, And Recovery Ice Streams, Weddell Sea, Antarctica, Ashley Marie Cirone
Provenance Tracing Of Glacial Sediment From The Foundation, Academy, And Recovery Ice Streams, Weddell Sea, Antarctica, Ashley Marie Cirone
Theses, Dissertations and Culminating Projects
This project seeks to advance our understanding of Antarctic Ice Sheet dynamics and to gain insight into the bedrock composition beneath the Antarctic Ice Sheet by “fingerprinting” ice streams that drain into the Ronne-Filchner Ice Shelf. The Ronne- Filchner Ice Shelf is the second largest ice shelf in Antarctica and receives ice drained from both the West and East Antarctic Ice Sheets through a series of ice streams. In response to global warming, this sector has the potential to contribute dramatically to sea level rise, especially from the Recovery Catchment. Till samples were collected from lateral moraines adjacent to the …
Targeting Sav Restoration At Lake Mattamuskeet Using Gis And Landsat 8 Data, Lindsey Shanks
Targeting Sav Restoration At Lake Mattamuskeet Using Gis And Landsat 8 Data, Lindsey Shanks
Theses, Dissertations and Culminating Projects
Lake Mattamuskeet, a large, shallow lake on the coast of North Carolina, has undergone water quality degradation and submerged aquatic vegetation (SAV) decline over recent years. Water depth and water clarity have been established as key drivers of SAV loss. To target locations for the restoration of SAV in the lake, an analysis that focuses on water clarity, water depth, and current SAV presence was developed. Two separate methodologies were conducted and compared to analyze water clarity in the lake. The first applied four years (2013-2016) of Landsat 8 imagery to a previously developed model that predicts water clarity from …
Determining Late Pleistocene To Early Holocene Deglaciation Of The Baltic Ice Lake Through Sedimentological And Geochemical Analysis Of Iodp Site M0064, April Lynn Kelly
Determining Late Pleistocene To Early Holocene Deglaciation Of The Baltic Ice Lake Through Sedimentological And Geochemical Analysis Of Iodp Site M0064, April Lynn Kelly
Theses, Dissertations and Culminating Projects
IODP Site M0064 within the Baltic Sea’s Hanô Bay was drilled to investigate the déglaciation history of the Scandinavian Ice Sheet (SIS) from the Late Pleistocene to the Holocene. This research aims to better understand how déglaciation speed, SIS drainage patterns, and changes in relative sea level influences sediment deposition within the Baltic Ice Lake (BIL) on a high-resolution timescale. Site M0064 contains diamicton at -47 - 9 mbsf, followed by an upward transition to cm-scale grey thinly laminated rhythmites at -8 mbsf, and a sharp 2.5 cm thick dark brown organic layer at -7.87 msbf, transitioning to reddish-brown thinly …
Grain Size And Organic Geochemistry Of Kattegat Sediment To Determine Paleoenvironments Of The Last Interglacial-Glacial Cycle, Taylor Ann Krolik
Grain Size And Organic Geochemistry Of Kattegat Sediment To Determine Paleoenvironments Of The Last Interglacial-Glacial Cycle, Taylor Ann Krolik
Theses, Dissertations and Culminating Projects
Periods of glaciation followed by deglaciation are a result of the complex processes that drive climate on Earth. To understand these processes and the types of climate that they induce, sediment cores can be analyzed to extract data to determine depositional environment and relative sea level in an area. This project will investigate the particle size and organic geochemistry from a sediment core (IODP Expedition 347, Hole M0060A) taken outside the Baltic Sea, at Anholt Loch which is located in the southern Kattegat. The objective of this study is to better understand the depositional environment and relative sea level changes …
