Book Description
This book documents and interprets the onshore Cenozoic temperate carbonate depositional system along the southern margin of Australia. These strata, deposited in four separate basins, together with the extensive modern marine system offshore, comprise the largest such cool-water carbonate system on the globe. The approach is classic and comparative but the information is a synthesis of recent research and new information. A brief section of introduction outlines the setting, modern comparative sedimentology offshore, and structure of the Cenozoic onshore. The core of the book is a detailed analysis and illustration of the four Eocene to Pleistocene successions. Deposits range from temperate carbonates, to biosiliceous spiculites, to marginal marine siliciclastics. Each unit is interpreted, as much as possible, based on our understanding of the modern offshore depositional system. A subsequent part concentrates on diagenesis both before and after the late Miocene uplift. It turns out that alteration in the two packages is entirely different. The preceding attributes of each succession are then interpreted on the basis of controlling factors such as tectonics, oceanography, climate, and glaciation of nearby Antarctica. This research has revealed new implications for the interpretation of specific attributes of cool-water carbonate sedimentology that could only be discovered from the rock record. Insights concerning cyclicity, reef mounds, biosiliceous deposition, and trophic resources are detailed in the next section. The concluding part focuses on global comparisons, especially the Mediterranean and New Zealand.

Book Description
Science, the growth of reliable knowledge, became a major triumph of the European Enlightenment in the seventeenth century, under the guise of ‘natural philosophy’: investigating what the earth and universe are made of and how things work. It took another century for the parallel subject ‘natural history’ to glimpse how the earth, its geography and its richly diverse life came to be. Later, geology and biology became intertwined as biogeohistory—an ever-changing environmental theatre hosting an ever-changing evolutionary play. This environmental theatre has shifted with the making and breaking of supercontinents, the birth and death of global oceans, and the rise and fall of global hothouses and ice ages. The evolutionary play begins with biostratigraphy, wherein fossils revealed deep time and ancient environments and built the first meaningful geological timescale, and ends with the still young science of palaeoceanography—central to which are microfossils, rich in information about the oceans and climates of the past. In Southern Limestones under Western Eyes, Brian McGowran recounts the history of biogeohistory itself: the ever-changing perceptions of rocks, fossils and landscapes, from the late 1600s to the present. McGowran’s focus is southern Australia, the north shore of the dying Australo-Antarctic Gulf, in an era bracketed by two catastrophes: the extinction of dinosaurs and the emergence of humans.

Book Description
This textbook deals with the most important items in Marine Geology, including some pioneer work. The list of topics has grown greatly in the last few decades beyond the items identified by Eugen Seibold as central and now includes prominently such things as methane and climate change; that is, the carbon cycle and the Earth system as a whole. Relevant geophysical, geochemical, sedimentological and paleontological methods are shortly described. They should allow the reader to comment on new results about plate tectonics, marine sedimentation from the coasts to the deep sea, climatological aspects, paleoceanology and the use of the sea floor. The text tries to transmit to the reader excitement of marine geological research both aboard and in modern laboratories. Basic mineralogical, geochemical, biological and other relevant data and a detailed list of books and symposia are given in an Appendix. This Introduction builds on the third edition of “The Sea Floor” by E. Seibold and W.H. Berger. While much of the original text was written by Seibold, a considerable portion of the material presented in this edition is new, taking into account the recent great shift in marine geological research, some of it with great relevance to human concerns arising in a rapidly changing world.

Book Description
Although it is generally accepted that the Arctic Ocean is a very sensitive and important region for changes in the global climate, this region is the last major physiographic province of the earth whose short-and long-term geological history is much less known in comparison to other ocean regions. This lack of knowledge is mainly caused by the major technological/logistic problems in reaching this harsh, ice-covered region with normal research vessels and in retrieving long and undisturbed sediment cores. During the the last about 20 years, however, several international and multidisciplinary ship expeditions, including the first scientific drilling on Lomonosov Ridge in 2004, a break-through in Arctic research, were carried out into the central Artic and its surrounding shelf seas. Results from these expeditions have greatly advanced our knowledge on Arctic Ocean paleoenvironments. Published syntheses about the knowledge on Arctic Ocean geology, on the other hand, are based on data available prior to 1990. A comprehensive compilation of data on Arctic Ocean paleoenvironment and its short-and long-term variability based on the huge amount of new data including the ACEX drilling data, has not been available yet. With this book, presenting (1) detailed information on glacio-marine sedimentary processes and geological proxies used for paleoenvironmental reconstructions, and (2) detailed geological data on modern environments, Quaternary variability on different time scales as well as the long-term climate history during Mesozoic-Tertiary times, this gap in knowledge will be filled. *Aimed at specialists and graduates *Presents background research, recent developments, and future trends *Written by a leading scholar and industry expert

Book Description
Methane is a strong climate-active gas, the concentration of which is rapidly increasing in the atmosphere. Vast methane reservoirs are hosted in seafloor sediments, both dissolved in pore fluids and trapped in gas hydrate. Cold seeps discharge significant amounts of this methane into the ocean. The rate of seabed methane discharge could be orders of magnitude higher than current estimates, creating considerable uncertainty. The extent of methane transfer from the seafloor to the water column and ultimately to the atmosphere is also uncertain. The seepage of methane and other hydrocarbons drives complex biogeochemical processes in marine sediments and the overlying water column. Seeps support chemosynthesis-based communities and impact the chemistry of the water column. Seeps may also play a critical role in ocean acidification and deoxygenation and can be geohazards, as well as a potential energy resource. Unraveling the complex and dynamic interactions and processes at marine seeps is crucial for our understanding of element cycling in the geo- and hydrosphere.

Book Description
Written by highly qualified Argentine scientists and scholars, this book focuses on the uninterrupted geological and paleontological record of Patagonia and Tierra del Fuego since the Miocene-Pliocene boundary to the arrival of man and modern times. This region is an outstanding area for research, with significant interest at the international level. It provides an updated overview of the scientific work in all related fields with a strong paleoclimatic approach. Patagonia has also been a sort of a "paleoclimatic bridge" between the Antarctic Peninsula and the more northerly land masses, since the final opening of the Drake Passage in the middle Miocene. Timely and comprehensive, The Late Cenozoic of Patagonia and Tierra del Fuego is the only monograph book written in English. * One-stop resource for paleontological information of the Late Cenozoic of Patagonia * Covers 5 million years in the uninterrupted history of Patagonia and Tierra del Fuego * Comprehensive coverage of the region written by highly qualified Argentine scientists and scholars
