Book Description
Interest in the interpretation of paleoenvironments has increased sharply in recent years with the growing importance of studies of the climate of the past. Whereever possible, researchers are attempting to interpret paleoenvironments by comparing ancient microfossil assemblages with modern populations. A CD-ROM (Win95/NT, MACOS 7.1) is included to interactively present the complex environmental data and the distributional patterns of individual diatom taxa.

Book Description
The present volume is the first in a series of two books dedicated to the paleoceanography of the Late Cenozoic ocean. The need for an updated synthesis on paleoceanographic science is urgent, owing to the huge and very diversified progress made in this domain during the last decade. In addition, no comprehensive monography still exists in this domain. This is quite incomprehensible in view of the contribution of paleoceanographic research to our present understanding of the dynamics of the climate-ocean system. The focus on the Late Cenozoic ocean responds to two constraints. Firstly, most quantitative methods, notably those based on micropaleontological approaches, cannot be used back in time beyond a few million years at most. Secondly, the last few million years, with their strong climate oscillations, show specific high frequency changes of the ocean with a relatively reduced influcence of tectonics. The first volume addresses quantitative methodologies to reconstruct the dynamics of the ocean andthe second, major aspects of the ocean system (thermohaline circulation, carbon cycle, productivity, sea level etc.) and will also present regional synthesis about the paleoceanography of major the oceanic basins. In both cases, the focus is the "open ocean leaving aside nearshore processes that depend too much onlocal conditions. In this first volume, we have gathered up-to-date methodologies for the measurement and quantitative interpretation of tracers and proxies in deep sea sediments that allow reconstruction of a few key past-properties of the ocean( temperature, salinity, sea-ice cover, seasonal gradients, pH, ventilation, oceanic currents, thermohaline circulation, and paleoproductivity). Chapters encompass physical methods (conventional grain-size studies, tomodensitometry, magnetic and mineralogical properties), most current biological proxies (planktic and benthic foraminifers, deep sea corals, diatoms, coccoliths, dinocysts and biomarkers) and key geochemical tracers (trace elements, stable isotopes, radiogenic isotopes, and U-series). Contributors to the book and members of the review panel are among the best scientists in their specialty. They represent major European and North American laboratories and thus provide a priori guarantees to the quality and updat of the entire book. Scientists and graduate students in paleoclimatology, paleoceanography, climate modeling, and undergraduate and graduate students in marine geology represent the target audience. This volume should be of interest for scientists involved in several international programs, such as those linked to the IPCC (IODP – Integrated Ocean Drilling Program; PAGES – Past Global Changes; IMAGES – Marine Global Changes; PMIP: Paleoclimate Intercomparison Project; several IGCP projects etc.), That is, all programs that require access to time series illustrating changes in the climate-ocean system. - Presents updated techniques and methods in paleoceanography - Reviews the state-of-the-art interpretation of proxies used for quantitative reconstruction of the climate-ocean system - Acts as a supplement for undergraduate and graduate courses in paleoceanography and marine geology

Book Description
This third volume in the Developments in Paleoenvironmental Research series deals with the major terrestrial, algal, and siliceous indicators used in paleolimnology. Other volumes deal with the acquisition and archiving of lake sediment cores, chronological techniques, and large-scale basin analysis methods (Volume 1), physical and geochemical parameters and methods (Volume 2), zoological techniques (Volume 4), and statistical and data handling methods (Volume 5). These monographs will provide sufficient detail and breadth to be useful handbooks for both seasoned practitioners as well as newcomers to the area of paleolimnology. Although the chapters in these volumes target mainly lacustrine settings, many of the techniques described can also be readily applied to fluvial, glacial, marine, estuarine, and peatland environments.

Book Description
The content is focused on benthic communities showing how they play an in important role in the river ecosystems. Provides also information on taxonomy of river-inhabiting algal groups, including phylogeny, distribution, collection, preservation and description of the most representative genera of algae in river benthic algal communities. The book also approaches the ecology of river algae not to mention the ecological factors influencing abundance, distribution and diversity of river benthic algal communities and their use as bio-indicators, providing an up-to-date information on taxonomy, ecology, methodology and uses, and a great source of research to everyone interested in freshwater algae, limnology, water quality assessment and biodiversity in river ecosystems.

Book Description
The freshwater diatom flora from arctic and subarctic regions of North America remains poorly known. The aim of this investigation is to improve our knowledge of diatoms in lakes from eastern subarctic Canada, and to provide a stronger foundation for the use of diatoms in limnological and palaeolimnological studies. To this end, we analysed the modern diatom assemblages in surficial sediments from 123 lakes in northern Québec and Labrador. The two study transects in Jamésie-Hudsonie (data set including 59 lakes and 38 environmental variables) and in Québec-Labrador (data set consisting of 64 lakes and 29 environmental variables) extend over a vast area from the boreal forest in the south to arctic tundra conditions in the north. Of a total of 516 diatom taxa in the Jamésie-Hudsonie data set, 218 species were used for the development of a transfer function for the reconstruction of dissolved organic carbon (DOC). In the Québec.Labrador data set, two inference models were developed for the reconstruction of water colour and alkalinity based on 128 of 303 diatom taxa. The majority of taxa belonging to this surprisingly species-rich boreal-subarctic diatom flora are illustrated in photographic plates, accompanied by a short description of the distribution of each taxon.

Book Description
Concerns about the effects of global climate change have focused attention on the vulnerability of circumpolar regions. This book offers a synthesis of the spectrum of techniques available for generating long-term environmental records from circumpolar lakes.

Book Description
An introduction to Ellef Ringnes Island, Prince Patrick Islandand Northern Ellesmere Island. From the preface This project was initiated in 1998 with the development of a surface diatomcalibration set for selected regions from the Arctic Islands.Under the study surface sediments, mosses,rock and otheravailable habitats were studied from 91 ponds and lakes.It became clear that the diatoms observed were new or undocumented. Detailed taxonomic studies were done at the Canadian Museum of Nature using SEM generated images andthe extensive Library. A must have for research in the Arctic
