Late-Holocene palaeoenvironmental changes at Lake Esmeralda (Vega Island, Antarctic Peninsula) based on a multi-proxy analysis of laminated lake sediment Article (PDF Available) in The Holocene. These are described in the Developments in Paleoenvironmental Research book series, including volume 8, which is dedicated to long-term environmental change in Arctic and Antarctic lakes (Pienitz.

The Holocene Climate Optimum (HCO) was a warm period during roughly the interval 9, to 5, years BP, with a thermal maximum around years has also been known by many other names, such as Altithermal, Climatic Optimum, Holocene Megathermal, Holocene Optimum, Holocene Thermal Maximum, Hypsithermal, and Mid-Holocene Warm Period.

This warm period was followed by a.

Pillans, P. Gibbard, in The Geologic Time Scale, Holocene Series. Holocene is the name for the most recent interval of Earth history and includes the present day. Although generally regarded as having begun 10 radiocarbon years, or the last 11 calibrated (i.e.

calendar) years, before present (i.e. ), the base of the Holocene is now assigned an age of 11 years b2k. Antarctic coastal marine habitat changes around the continent also coincided with increasing sea-ice extent and outlet glacial advances during the mid-Holocene.

In view of the diverse environmental changes that occurred around the Earth during this period, it is suggested that Antarctic coastal areas were responding to a mid-Holocene climatic.

Holocene environmental changes in the Maeho Lagoon Based on the core lithology and cluster analysis of diatom remains, the sediments of core PMR‐2 can be divided into five zones.

The polar regions have experienced some remarkable environmental changes in recent decades, such as the Holocene environmental changes in Antarctic coastal areas book ozone hole, the loss of large amounts of sea ice from the Arctic Ocean and major warming on the Antarctic Peninsula.

The polar regions are also predicted to warm more than any other region on Earth over the next century if greenhouse gas concentrations continue to rise.5/5(1).

It is important for the reader to understand clearly the objectives of these papers. They are not an attempt to provide accurate predictions of what is going to happen in Australia over the next few decades.

Rather they represent sensitivity studies, designed to illustrate to what extent we as a nation are dependent on the climate and likely to be affected by climatic change, and attempts to.

Two sediment cores from the eastern coastal region of Marajó Island, Pará State, northern Brazil have been studied by pollen analysis to reconstruct late Holocene mangrove dynamics and environmental changes. Seven AMS radiocarbon dates provide time control.

In the School of Natural and Social Sciences, pure and applied research into climate and environmental change is promoted under the marque of the Centre for Environmental Change and Quaternary Research (CECQR). This centre, which was established inintegrates the activities of several colleagues here and abroad who work on geochronology, climate change, environmental change and human.

Abstract. Time series for the Quaternary, which covers the past million years, reveal large, continuous, and sometimes abrupt ecological and environmental changes on time scales of decades to thousands of by: The beach subsequently formed separated the estuary from the sea and changed it into a freshwater lake.

Accumulation of moss and gyttja, containing a freshwater diatom assemblage, marks the final late Holocene stage of this coastal sedimentary sequence, which can be considered as typical for deglaciation periods in the maritime Antarctic. Arctic, Antarctic, and Alpine Research publishes research and book reviews on any scientific or cultural aspect of Arctic, Antarctic, and alpine environments.

Figure 1B, excludes KY and OCEGGC If all proxies are included, as in figure 1A, this reconstruction shows a very flat Holocene Climatic Optimum (HCO) from BP to BP and then a steady decline in temperatures to the Little Ice Age (LIA) around years ago ( BP or about AD).

Dr. Ramenzoni is an environmental anthropologist specialized in human behavioral ecology, coastal communities, and marine and coastal policies. Through a mixed methods approach, she studies how socio-ecological factors shape human adaptation, the impact of environmental uncertainty on decisions about resource use, and household nutrition in.

Environmental pollution. We conduct research on how environmental pollutants and plastics are included in Arctic food chains, their sources, accumulation and long-term trends.

We study health effects in species high up in the food chain, and map how climate change affects pollutants in the European Arctic. A.V. Maslennikova, V.N. Udachin and P.G.

About 78% of the mass of the atmosphere is composed of nitrogen gas (N 2), while 21% is oxygen (O 2), % argon (Ar), and % carbon dioxide (CO 2).The rest is various trace gases, including potentially toxic ones such as ozone (O 3) and sulphur dioxide. Global warming may bring changes in environmental conditions in diverse geographical areas, and it will in turn bring changes in structures and functions of ecosystems (Grimm et al.

Research on changes in the climate system on decade-to-century timescales has achieved notable successes in the past decade.

The effective use of the paleoclimate record has revealed attributes of natural climate variability and has provided a context for the study of present and future global change. Although many notable physical, biological and environmental changes have recently occurred there, especially around the Antarctic Peninsula during the last 50 yr (MercerThomas et al.Rott et al.Vaughan & DoakeSmith et al.Doran et al.Marshall et al.
