FIRE AND CATASTROPHIC FLOODING, FOURMILE CATCHMENT, FRONT RANGE, COLORADO

Students and faculty of the Keck Colorado Project will make field measurements and collect samples to help characterize the: (1) importance of fire in the critical zone; (2) the geomorphic significance of catastrophic floods in channel and floodplain evolution; and (3) the variable effects of the September 2013 floods from the upper to lower Fourmile […]

CALIBRATING NATURAL BASALTIC LAVA FLOWS WITH LARGE-SCALE LAVA EXPERIMENTS

Participants will investigate the behavior and morphology of basaltic lava flows from two very different but related perspectives: field observations of historic basaltic lava flows in Iceland and large-scale lava flow experiments conducted at Syracuse University. Experiments will be designed to constrain the factors that control various features found in the natural lavas. What: The […]

GEOLOGICAL HAZARDS, CLIMATE CHANGE, AND HUMAN/ECOSYSTEMS RESILIENCE IN THE ISLANDS OF THE FOUR MOUNTAINS, ALASKA

Project Director: Kirsten Nicolaysen (Whitman College) Number of students: 3 Approximate dates: July 24 to August 20th Project summaryAssessing the degree to which geological hazards in the Aleutian archipelago disrupted prehistoric human and ecological systems has important lessons for current inhabitants of the northern Pacific Rim. The Islands of Four Mountains region embodies environmental instabilities […]

HOLOCENE CLIMATIC CHANGE AND ACTIVE TECTONICS IN THE PERUVIAN ANDES: IMPACTS ON GLACIERS AND LAKES

What: We will generate continuous records of mountain glaciation in Peru that span the Holocene (~12 ka to present) through an approach that combines the acquisition and analysis of lake sediment cores with moraine dating using both lichenometry and cosmogenic radionuclides (10Be and 26Al).   In addition, we will also focus on determining the average rate […]

ANTARCTIC PLIOCENE AND LOWER PLEISTOCENE (GELASIAN) PALEOCLIMATE RECONSTRUCTED FROM OCEAN DRILLING PROGRAM WEDDELL SEA CORES

Investigation of the sedimentary record of Antarctic climate change with a focus on Pliocene of the Weddell Sea. Today the densest ocean water, Antarctic Bottom Water, is formed in the Weddell Sea.  Yet, the sedimentary history of the Weddell Sea basin is poorly studied. Students will measure and sample these cores, and have access to […]

GEOMORPHOLOGIC AND PALEOENVIRONMENTAL CHANGE IN GLACIER NATIONAL PARK, MONTANA

What: We will be working on reconstructing past environmental and geomorphic conditions in Glacier National Park through collection and analysis of lake sediment cores. There is broad interest in the future of our National Park system, particularly Glacier National Park, which is sensitive to climate change through glacial retreat and ecosystem adjustments. This research project […]

EXPLORING THE PROTEROZOIC BIG SKY OROGENY IN SW MONTANA: METASUPRACRUSTAL ROCKS OF THE RUBY RANGE

What:  The southwest Montana project aims to characterize the protoliths, the grade and timing of metamorphism, and the intensity and nature of tectonism of metasupracrustal rocks that occur along the western flank of the Ruby Range, and to integrate these findings into our developing understanding of the 1.8-1.7 Ga Big Sky orogeny, an arc-continent collision […]

RESILIENCE OF ENDANGERED ACROPORA SP. CORALS IN BELIZE. WHY IS CORAL GARDENS REEF THRIVING?

At a time of dramatic worldwide coral reef decline, much of modern coral reef science has necessarily focused on what contributes to the demise of coral reef systems. But for reef conservation and protection efforts to become significantly more effective, it is increasingly important to focus on what actually makes a reef thrive. The aim […]

TECTONIC EVOLUTION OF THE CHUGACH-PRINCE WILLIAM TERRANE, SOUTH CENTRAL ALASKA

What: This project focuses on the tectonic evolution of the Chugach-Prince William terrane in south central Alaska, and it is a continuation of our 2011-13 Keck projects.  The Chugach-Prince William terrane is a thick accretionary complex dominated by Campanian-Paleocene (c. 75-55 Ma) trench fill turbidites that were likely derived from the uplift and exhumation of terranes […]
