Freshwater outbursts to the oceans from glacial Lake Agassiz and their role in climate change during the last deglaciation
Lake Agassiz was the largest lake in North America during the last deglaciation. As the Laurentide Ice Sheet (LIS) retreated, large volumes of water stored in this proglacial lake were episodically released into the oceans. These waters were variably routed to the Gulf of Mexico, Arctic Ocean, North Atlantic Ocean, and Hudson Bay. During this period, the three largest cooling events in the Nort...
متن کاملExtensive Deposits on the Pacific Plate from Late Pleistocene North American Glacial Lake Outbursts
One of the major unresolved issues of the Late Pleistocene catastrophic-flood events in the northwestern United States (e.g., from glacial Lake Missoula) has been what happened when the flood discharge reached the ocean. This study compiles available 3.5-kHz high-resolution and airgun seismic reflection data, long-range sidescan sonar images, and sediment core data to define the distribution of...
متن کاملSelf-organized Reservoirs and Their Hierarchies
We investigate how unsupervised training of recurrent neural networks (RNNs) and their deep hierarchies can benefit a supervised task like temporal pattern detection. The RNNs are fully and fast trained by unsupervised algorithms and only supervised feed-forward readouts are used. The unsupervised RNNs are shown to perform better in a rigorous comparison against state-of-art random reservoir ne...
متن کاملTopological Characteristics of Oil and Gas Reservoirs and Their Applications
At present no company develops oil and gas fields without constructing geologic and hydrodynamic models. This is due in particular to the fact that recently the emphasis in design, planning and monitoring has shifted to overdissected and low-permeability reservoirs. To assess economic efficiency and optimal placement of wells and to predict hydrocarbon production levels, it is important to have...
متن کاملOrigin and Dynamical Evolution of Comets and Their Reservoirs
This text was originally written to accompany a series of lectures that I gave at the ‘35th Saas-Fee advanced course’ in Switzerland and at the Institute for Astronomy of the University of Hawaii. It reviews my current understanding of the dynamics of comets and of the origin and primordial sculpting of their reservoirs. It starts discussing the structure of the Kuiper belt and the current dyna...
