Questions and clarity: insights from applying computational methods to paleoclimate archives
Full text linkSubmitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Marine Geology & Geophysics at the Massachusetts Institute of Technology and the Woods Hole Oceanographic Institution May 2022.It is a scientifically accepted fact that the Earth’s climate is presently undergoing significant changes with the potential for immense negative impacts on human society. As evidence of these impacts become clear and common, it becomes ever more important to constrain the nature, magnitude, and speed of changes to Earth systems. A fundamentally important tool to this understanding is the Earth’s past, recorded in the geologic record. There, lie examples of climate change under various forcings: important data for understanding the fundamental dynamics of climate change on our planet. However, when a climate signal is
written in the geologic record, it is coded into the language of proxies and distorted by time. This thesis endeavors to decode that record using a variety of computational methods on a number of challenging proxies, to draw more information from the climate past than has previously been possible. First, machine learning and computer vision are used to decipher the primary, centimeter-scale textures of carbonate deposits in Searles Valley and Mono Lake, California. This work is able to connect facies in the tufa at Searles, grown during the Last Glacial Period, and those forming presently at Mono Lake. Next, the tracks of icebergs purged during Heinrich Events are simulated using the MIT General Circulation Model. This work, running multiple experiments exploring different aspects internal and external to the icebergs, reveals wind and sediment partitioning as centrally important to the spatial
extent of Heinrich Layers. Each of these works considers a traditional geologic archive – a carbonate facies, a marine sediment layer – and uses computational methods to approach that archive from a different perspective. By applying these new methods, more information can be gleaned from the geologic record, building a richer narrative of the Earth’s climate history. The final chapter of this thesis discusses effective teaching and strategies for building communities to support teaching practice in Earth Science departments.This thesis work was funded by the MIT EAPS Rasmussen and Whiteman Fellowships, NSF Project Number NSF-EAR-1903544, and the WHOI Academic Programs Office

No full textMegaptera novaeangliae (humpback whale) - CCSN-07-181 - female - 9.85 m - Pelvic location - Seacoast Science Center. The fresh carcass of a 32.3-foot (985 cm), 2-year-old female named “Tofu” was found floating about 4 miles off Race Point, Provincetown, Barnstable County, MA on the mourning of 24 June. It was towed to a marina in Dennis and trucked to the Bourne landfill where it was necropsied on 26 June. The carcass weighed about 10 tons. It was found to have a large bruised area from the ventral side of the head of its right humerus and upper chest, down to its upper belly, caused by a vessel strike. No bones were broken. It took 5.5 hours to conduct the necropsy and to remove the entire skeleton. The whole right rack of baleen and the anterior 2/3 of the left rack were removed and preserved in one piece, each. The posterior 1/3 of the left rack was taken by the Cape Cod Stranding Network to be used for education. The skeleton was donated to the Seacoast Science Center, Rye, N

The fresh carcass of a 44-foot (1340 cm), 6-year-old female named “Beacon” washed ashore at Newcomb Hollow Beach, Wellfleet, MA on the Cape Cod National Seashore but the Park Service would not allow vehicle access. Dave Taylor removed both pelvic bones during the necropsy on 12 December. The cause of death was unknown. The carcass washed off the beach during a storm and was found on Nauset Beach, Orleans on ??. By this time the carcass was deflated. All of the ribs, as well as the cervical, thoracic and lumbar vertebrae were missing. Two of the vertebrae were found on a beach in Wellfleet. On 5 January 2005, an effort was made to salvage the skull and jaws by hand and with a truck winch in bitter, blowing sleet, but only the jaws could be salvaged. A section at the left rear of the cranium was missing. Around 8 January the carcass washed off again and was eventually found well up into Eastham Harbor where it lodged on a gravel bar and was iced in for the winter. In the spring it washed ashore up against a private pier about 200 yards east of the Orleans rotary. On 11 May the Eastham Natural Resource Officer, Henry Lend and others pulled it into deeper water and anchored it. On 14 May it was towed to a nearby boat ramp where we salvaged the slightly damaged skull, both flippers, and the caudal vertebrae. The skull measures about 11.5 feet long and 6.5 feet wide. Skeleton was given to Northeastern University
