Variability Of Lacustrine Sediment Proxy Responses To Late Holocene Climate Change As Modified By Lake Specific Processes: A Review Of Ecological And Geophysical Processes Across Northern And Eastern Iceland, Mallory Mintz
Independent Study Project (ISP) Collection
Consistenly-deposited lake sediments provide some of the highest resolution records of local and global climates in the past, offering the potential to better understand modern climate change in the context of past climate variability. In relating proxies to their respective climate regimes, the environmental cues that the specific proxies reacted to must be isolated from the general noise of possible local influences. In this investigation, biogenic silica (BSi), total organic carbon (TOC), δ13C values, and carbon: nitrogen ratios were analyzed between lakes through northern Iceland, to review possible complicating factors specific to the use of lacustrine proxies in the interpretation …
Proxy Dating In Iceland Testing The Validity Of Silene Acaulis As A Phytometric Proxy, Madelyn Grant
Proxy Dating In Iceland Testing The Validity Of Silene Acaulis As A Phytometric Proxy, Madelyn Grant
Independent Study Project (ISP) Collection
Climate change is causing drastic changes in the cryosphere, particularly in the Arctic region where average warming is 1.9 times greater than in the rest of the world due to Arctic amplification. Understanding the response of essential climate variables such as glaciers and ice caps to rapid Arctic warming is essential to predicting future changes in the Arctic region and around the world. Proxy dating methods can help construct a record of warming-induced glacial retreat in areas where long-term monitoring systems are not in place. In Arctic regions, the cushion plant Silene acaulis represents one of the only feasible proxies …
Investigating Effects Of Climate Change On Glaciers And Proglacial Landscapes In Southeast Iceland: Fluvioglacial Behavior Of Sólheimajökull And Seljavallajökull, Roberta B.C. Miller
Investigating Effects Of Climate Change On Glaciers And Proglacial Landscapes In Southeast Iceland: Fluvioglacial Behavior Of Sólheimajökull And Seljavallajökull, Roberta B.C. Miller
Independent Study Project (ISP) Collection
The Seljavallajökull glacier, part of the Eyjafjallajökull glacier system, and Sólheimajökull, part of the Mýrdalsjökull glacier system, are two glaciers that extend into valleys in the southeast part of Iceland. Due to climate warming, both of these glaciers are part of a melting ice cap. They are located nearby to one another, and Sólheimajökull has been extensively studied for its outwash plain sedimentology, retreat history, pro-glacial geomorphology and has been steadily monitored by the Glaciological Society of Iceland. Seljavallajökull has also been monitored by this group, but it has not been studied for sediment profiles and landscape chronology as Sólheimajökull …
Geospasial Indonesia: The Utilization Of Spatial Data Through Geographic Information Systems Across Indonesia In Various Environmental Contexts, Kaitlyn Bretz
Independent Study Project (ISP) Collection
Spatial planning and mapping in Indonesia have had a precarious history for the past several decades. Laws controlling the creation of maps for land use planning have fluctuated greatly between executive administrations and the country is still struggling to create a single, unified national map. With the One Map Policy the future of mapping is optimistic, but in the meantime spatial data analyses are lacking. Geographic information systems (GIS) is a computerized system for the capture, storage, querying, analysis, and display of spatial data, and is used predominately by the government, private companies, and nongovernmental organizations (NGOs) across Indonesia. Community …
