The author served as a stratigrapher with both expedi tions . Various members of the staff of the Department of Geology, The Ohio State University, as well as some specialists from the outside were consulted in the laboratory studies for the pre paration of this report. Dr. George E. Moore supervised the petrographic work and critically reviewed the manuscript. Dr. J. M. Schopf examined the coal and plant fossils, and provided information concerning their age and environmental significance. Drs. Richard P. Goldthwait and Colin B. B.

2017 Chicxulub Revealed
THE UNIVERSITY TEXAS OF AUSTIN AT JACKSON• SCHOOL GEOSCIENCES OF 2017 NEWSLETTER• Newsletter2 017 Chicxulub Revealed A first look at rocks from the crater left by the asteroid that wiped out non-avian dinosaurs WELCOME Dear Alumni and Friends he devastation that Hurricane Harvey brought to Texas communities in August was a tragic reminder of how vital it is to understand our planet and T its processes. Shortly after the hurricane struck, our scientists, through our Rapid Response program, began to conduct research to understand how Harvey has impacted the coast and offshore Gulf of Mexico. This research will help determine the best ways to deal with many coastal issues in the aftermath of the storm, and how we might better prepare for such events in the future. You can read more about the mission on page 18.

This is what we strive to do here at the THE CHICXULUB CRATER FORMED BY THE Jackson School of Geosciences. This year’s Newsletter holds some tremendous examples.

Riding on the leading edge of the moving North American plate, Oregon reflects the underlying mecha- nism of the plate collision boundary in virtually all aspects of its geology. In the seven years since the fourth edition was written, an irregular but continuing drumbeat of earthquakes reminds us of the forces beneath our feet and the need to prepare for catastrophic changes be they quakes, volcanoes, tsunamis, floods, or massive earth movements. Most profound is the discovery of irrefutable evidence that these catastrophes have been visited on the state quite regularly over the past few thousands of years as well as the absolute surety that similar disasters will oc- cur in the near and distant future. -
Retreat of the Smith Sound Ice Stream in the Early Holocene

Nares Strait, a major connection between the Arctic Ocean and Baffin Bay, was blocked by coalescent Innuitian and Greenlandice sheets duringthe last glaciation.This paper focuses on the eventsandprocesses leading to the openingofthe strait and the environmental response to establishment of the Arctic-Atlantic throughflow. The study is based on sedimentological, mineralogical and foraminiferal analyses of radiocarbon-dated cores 2001LSSL-0014PC and TC from northern Baffin Bay. Radiocarbon dates on benthic foraminifera were calibrated with DR = 220Æ20 years. Basal compact pebbly mud is interpreted as a subglacial deposit formed by glacial overriding of unconsolidated marine sediments. It is overlain by ice-proximal (red/grey laminated, ice-proximal glaciomarine unit barren of foraminifera and containing >2 mm clasts interpreted as ice-rafted debris) to ice-distal (calcareous, grey pebbly mud with foraminifera indicative of a stratified water column with chilled Atlantic Water fauna and species associated with perennial and then seasonal sea ice cover) glacial marine sediment units. The age model indicates ice retreat into Smith Sound as early as c. 11.7 and as late as c. 11.2 cal. ka BP followed by progressively more distal glaciomarine conditions as the ice margin retreated toward the Kennedy Channel.

The Geochemical Response of Sedimentary Archives to Rapid Recent Glacier Retreat at the Western Antarctic Peninsula (WAP): from Source to Sink
The geochemical response of sedimentary archives to rapid recent glacier retreat at the western Antarctic Peninsula (WAP): from source to sink Geochemische Reaktion von Sedimentarchiven auf den schnellen rezenten Gletscherrückzug auf der Westantarktischen Halbinsel: von der Quelle zur Senke Dissertation zur Erlangung des Grades eines Doktors der Naturwissenschaften – Dr. rer. nat. – angenommen bei der Fakultät für Mathematik und Naturwissenschaften der Carl von Ossietzky Universität Oldenburg von Patrick Monien geboren am 15.02.1977 in Oldenburg Erstgutachter: Prof. Dr. Hans-Jürgen Brumsack Zweitgutachter: Prof. Dr. Jürgen Rullkötter Eingereicht am: 02. Oktober 2013 Disputation am: 11. Februar 2014 Abstract Abstract Since the middle of the 20th century the western Antarctic Peninsula (WAP) belongs to the regions with the most rapid warming on Earth and is therefore considered to be one of the hotspots of climate change. During the last six decades an increase in mean annual air temperatures of more than 3°C is observed along the WAP causing severe changes in local cryospheric and ecosystems. The overarching aim of this thesis is to assess, whether the documented temperature increase and associated glacier retreat at WAP is reflected in the geochemistry of sedimentary records and if such episodes did occur during other periods within the Holocene. Moreover, this work focusses on biogeochemical processes in maritime Antarctic sediments and their implications for local benthic and pelagic communities. The rapid recent warming in the WAP region has already been related to significant changes in the distribution of one of the regions’ upper-trophic level predators, such as the Chinstrap (Pygoscelis antarctica) Adélie (P. adéliae) and Gentoo (P. -
