In this study, Candida Antarctica lipase B (CalB) was covalently immobilized on the surface of graphene oxide (GO) nanoparticles by sortase-mediated immobilization as well as a chemical attachment approach. Sortase is a transpeptidase that provides one-step purification and targeted...

Plastic debris is transported by ocean currents over long distances, reaching remote areas, far from its original source. In Polar Regions, microplastics (MPs) may come from local activities or be transported from lower latitudes, the former being the likely source. Although historically...

The potential impact of coronavirus on human impact both in Antarctica through tourism and scientific research as well as the Antarctic Treat System is reviewed over three time periods. In the short term, to April 2021, Antarctic tourism and field-based science will be severely reduced. The...

As the most inhospitable continent on Earth, Antarctica has more than 90% of its territory covered with ice and contains around 70% of all potable water in the world. Its proximity to South America is especially relevant to Brazil, which includes it in the country's strategic surrounding area....

Antarctica was only discovered in 1773 by Captain Cook, who first crossed the southern polar circle searching for the terra australis. It constitutes about 9% of the Earth's landmass and almost 14 million square kilometres of its surface. Approximately 98% of Antarctica is covered by ice, which...

This book discusses to what extent the precautionary approach to fisheries management is reflected in the MSC Fisheries Standard and in the certification of four clusters of fisheries in polar waters. Certification according to private sustainability standards (ecolabelling) has become an...

Being the most inhospitable continent in Earth, Antarctica has more than 90% of its territory covered with ice and contains around 70% of all drinkable water in the world. Its proximity to South America turns this region into especially relevant to Brazil, being included to the country's...

The purpose of this paper is to determine the status of Antarctica in international law, taking into account the effect of the Antarctic Treaty on Antarctica's legal status, and the extent to which this has been altered or affected by the major additions to the Antarctic Treaty System since its...

Maritime activity in the Antarctic region goes back to the 18th Century. It evolved from exploration and discoveries to commercial activities, especially sealing and whaling. Antarctic tourism is a more recent phenomenon, developing gradually from the 1960s. Today, more than 20.000 tourists...

In 2009, the 1959 Antarctic Treaty celebrates its fiftieth anniversary. Over its fifty-year existence the Treaty and the Antarctic Treaty System (ATS) built upon it, have promoted freedom of scientific research in Antarctica and the Southern Ocean. Despite the many successes of the Antarctic...

Florian C. Kleemann erarbeitet erstmals für die internationale Logistik ein fundiertes Regionenprofil der Antarktis, des weißen Kontinents am südlichen Ende der Welt. Der Autor analysiert dabei logistische Rahmenbedingungen im Bereich Politik, Recht, Wirtschaft und Klima. Fallstudienbasiert...

Purpose – Tourism in Antarctica is rapidly growing and diversifying, which raises concerns about its impacts and the robustness of the current regulatory regime. Focusing on the analysis of past developments and trends of Antarctic tourism, this paper aims to describe the future opportunities...

This article provides general background on the development of tourism in Antarctica and environmental concerns raised by it. However, the major part of it reports on and interprets the results from a survey of tourists visiting Antarctica on a cruise ship. Particular attention is given to the...

This report contains environmental profiles for the 25 Overseas countries and territories (OCTs) associated with the European Union. These environmental profiles are set in a socio-economic developmental perspective so that the findings can be used to assist in programming projects in the...

Within the Antarctic Treaty Consultative Meetings, momentum has been building to define and manage the human footprint of research stations in Antarctica. This has been reflected by national operators and researchers offering varied approaches to measuring "footprint". By not having a standard...

The paper describes the design process of a photovoltaic (PV)-wind power system to be installed in the very challenging ambient conditions of the French-Italian Antarctic Base. Concordia Base has been built with the collaboration of Italian consortium PRNA, French Polar Institute IPEV and...

Provides background on the development and nature of Antarctic tourism and associated environmental issues, as well as agreements and regulations affecting environmental management in Antarctica. Following an outline of the survey methodology and provision of information on the socioeconomic...

Reports the results of surveys of Antarctic cruise ship passengers on the ‘Akademik Ioffe’ who undertook their Antarctic journey in January 2003. The prime purposes of the surveys were to determine the socio-economic profile of these travellers, evaluate the importance of Antarctic wildlife...

This paper discusses high-level environmental policy objectives under the Antarctic Treaty System (ATS), and their relation to Strategic Environmental Assessment (SEA). It reviews the need for SEA in Antarctica; discusses existing ATS strategic processes and the impediments to achieving the...

Rapid climate changes which have been observed over the recent years in both polar regions of the Earth, directly or indirectly affect vegetation dynamics. This article presents the main directions of the changes taking place in the recent years in tundra communities of both polar regions, based...

Rapid changes in the major environmental variables like: temperature, wind and precipitation have occurred in the Antarctic region during the last 50 years. In this very sensitive region, even small changes can potentially lead to major environmental perturbations. Then the climate change poses...

<p>The geographic position, astronomic factors (e.g. the Earth's maximum distance from the Sun during winter), ice cover and altitude are the main factors affecting the climate of the Antarctic, which is the coldest place on Earth. Parts of Antarctica are facing the most rapid rates of...</p>

An important question stated in the presented paper is: Could rotifers be the indicators of climate change in the Antarctic environments? Rotifers are one of the most important components of the invertebrate fauna of the Antarctic freshwater and terrestrial ecosystems. However, investigations of...

This study presents changes in the concentrations of nitrogen and phosphorus in two streams in Western Antarctica (Admiralty Bay, King George Island, South Shetlands) that differ in trophic status. The results suggest a decline in concentrations of the determined forms of N and P between 2001...
