International Law and Arctic Shipping

The Arctic Ocean is gradually experiencing the effects of globalisation as a result of climate change, ice melt, and the emergence of a range of shipping activity in the sub-Arctic, along the Arctic coast, and within the central Arctic Ocean. While international law has been prominent in any consideration to date of the shipping issues associated with the Northern Sea Route (Northeast Passage) and the Northwest Passage, the development of trans-Arctic shipping and associated new shipping routes throughout various parts of the Arctic have the potential to raise a series of new Arctic international legal issues which have never before considered in an Arctic context. This paper will assess those issues with reference to how the navigational regime under the 1982 United Nations Convention on the Law of the Sea applies in the Arctic and how the freedom of navigation exercised through international straits and the high seas may in an Arctic setting need to be balanced against the legitimate rights and interests of the Arctic littoral states, including indigenous peoples. Solutions to these issues consistent with contemporary international law will be considered, including whether there may be a need to develop distinctive responses to some of these questions

GNSS transpolar earth reflectometry exploriNg system (G-TERN): mission concept

The global navigation satellite system (GNSS) Transpolar Earth Reflectometry exploriNg system (G-TERN) was proposed in response to ESA's Earth Explorer 9 revised call by a team of 33 multi-disciplinary scientists. The primary objective of the mission is to quantify at high spatio-temporal resolution crucial characteristics, processes and interactions between sea ice, and other Earth system components in order to advance the understanding and prediction of climate change and its impacts on the environment and society. The objective is articulated through three key questions. 1) In a rapidly changing Arctic regime and under the resilient Antarctic sea ice trend, how will highly dynamic forcings and couplings between the various components of the ocean, atmosphere, and cryosphere modify or influence the processes governing the characteristics of the sea ice cover (ice production, growth, deformation, and melt)? 2) What are the impacts of extreme events and feedback mechanisms on sea ice evolution? 3) What are the effects of the cryosphere behaviors, either rapidly changing or resiliently stable, on the global oceanic and atmospheric circulation and mid-latitude extreme events? To contribute answering these questions, G-TERN will measure key parameters of the sea ice, the oceans, and the atmosphere with frequent and dense coverage over polar areas, becoming a “dynamic mapper”of the ice conditions, the ice production, and the loss in multiple time and space scales, and surrounding environment. Over polar areas, the G-TERN will measure sea ice surface elevation (<;10 cm precision), roughness, and polarimetry aspects at 30-km resolution and 3-days full coverage. G-TERN will implement the interferometric GNSS reflectometry concept, from a single satellite in near-polar orbit with capability for 12 simultaneous observations. Unlike currently orbiting GNSS reflectometry missions, the G-TERN uses the full GNSS available bandwidth to improve its ranging measurements. The lifetime would be 2025-2030 or optimally 2025-2035, covering key stages of the transition toward a nearly ice-free Arctic Ocean in summer. This paper describes the mission objectives, it reviews its measurement techniques, summarizes the suggested implementation, and finally, it estimates the expected performance.Peer ReviewedPostprint (published version

Towards a better use of arctic marine infrastructure: EU-PolarNet, EUROFLEETS2 and ARICE

The Polar Regions may seem remote, but the observed rapid changes now affecting both the Arctic and Antarctic regions have resulted in significant consequences for the weather and climate in lower latitudes, including Europe. Environmental changes being observed, particularly in the Arctic, are a clear indication of the impending shifts that will increasingly affect European environment, society and industry. Changes in the Polar Regions present societal challenges, but also economic opportunities for Europe and the world. Science is a vital tool in understanding what is driving the rapid changes being observed at high latitudes. Research is also necessary to make our climate models and forecasting more realistic by identifying and reducing important sources of uncertainty that may impair reliable prediction. However the scale of many of the questions being posed is now recognised as being beyond the capabilities of individual nations and strong international cooperation is needed to overcome these challenges. There is often a need to obtain data from geographically widely separated areas of the Polar Regions and these need complementary observational schemes to be implemented for valid inter-comparisons. Similarly the costs of operating infrastructure in Polar Regions are becoming increasingly challenging and there is a need therefore to cooperate on infrastructure access and shared costs to optimise the support of larger research programmes. The presentation will introduce three European projects: EU-PolarNet, EUROFLEETS2 and ARICE which actively work on improving infrastructure development and access in the Polar Regions in cooperation with international partners. The examples given are from the Arctic Ocean but similar models of transnational access and infrastructure sharing will apply for the Antarctic.Peer Reviewe

Oceans governance in the Arctic

Global warming is bringing rapid change to the Arctic. The melting of sea ice and glaciers is increasing faster than scientists predicted even a year ago. Environmental change is forcing legal and economic developments, which in turn will have serious environmental and social consequences. However, the potential for conflict has been greatly exaggerated. The 1982 United Nations Convention on the Law of the Sea (LOS C) has established the international legal regime governing the division of ocean space, sovereign rights over ocean resources, protection of the marine environment and the conduct of activities in and under the Arctic Ocean. Furtherrmore, a number of global environmental and maritime conventions apply to the Arctic. All the land territory, with its resources, is subject to national jurisdiction, as are the maritime zones proceeding seawards to the limits set our in the LOSe. While there is no multilateral political organisation with the power to regulate activities or to take legally binding decisions, there is a cooperative mechanism in the Arctic Council. Once all the maritime boundaries in the Arctic are delimited, the exploitation of resources can begin. However, first, precautionary measures should be adopted to ensure that the environment is protected as much as possible from increases in shipping and fishing as well as oil and gas development. This would require the elaboration of a regional seas agreement for the Arctic, incorporating elements of the Arctic Council, that reiterates the general principles in Part XII of the LOSC as well as those in the UN Fish Stocks Agreement, including the precautionary approach and the ecosystem approach

Global Security, Climate Change, and the Arctic

This issue of Swords and Ploughshares examines the complex set of global security challenges that are emerging as a result of warmer temperatures and melting ice in the Arctic region. For policymakers and analysts alike, the contemporary Arctic presents a particularly acute convergence of compelling problems and opportunities related to global security, foreign affairs, climate change, environmentalism, international law, energy economics, and the rights of indigenous populations. The goals of this publication are two-fold: to provide thoughtful analysis of recent developments in the Arctic both from scientific and geopolitical perspectives; and to offer careful and informed assessments of how evolving conditions in the Arctic might impact the broader global security framework and relations between the international actors involved, not to mention the region’s inhabitants and ecosystem. The articles in this issue were contributed by each of four panelists invited by the Program in Arms Control, Disarmament, and International Security (ACDIS), the European Union Center, and the Russian, East European, and Eurasian Center at the University of Illinois to participate in a November 2009 symposium entitled “Global Security, Climate Change, and the Arctic: Implications of an Open Northwest Passage.” The symposium and this publication were supported through grants to the host centers from the European Commission, the US Department of Education (Title VI international education program), and the John D. and Catherine T. MacArthur Foundation.published or submitted for publicationnot peer reviewe

Underwater radiated noise levels of a research icebreaker in the central Arctic Ocean

U.S. Coast Guard Cutter Healy\u27s underwater radiated noise signature was characterized in the central Arctic Ocean during different types of ice-breaking operations. Propulsion modes included transit in variable ice cover, breaking heavy ice with backing-and-ramming maneuvers, and dynamic positioning with the bow thruster in operation. Compared to open-water transit, Healy\u27s noise signature increased approximately 10 dB between 20 Hz and 2 kHz when breaking ice. The highest noise levels resulted while the ship was engaged in backing-and-ramming maneuvers, owing to cavitation when operating the propellers astern or in opposing directions. In frequency bands centered near 10, 50, and 100 Hz, source levels reached 190–200 dB re: 1 μPa at 1 m (full octave band) during ice-breaking operations

Retrieving Precipitable Water Vapor From Shipborne Multi‐GNSS Observations

©2019. American Geophysical UnionPrecipitable water vapor (PWV) is an important parameter for climate research and a crucial factor to achieve high accuracy in satellite geodesy and satellite altimetry. Currently Global Navigation Satellite System (GNSS) PWV retrieval using static Precise Point Positioning is limited to ground stations. We demonstrated the PWV retrieval using kinematic Precise Point Positioning method with shipborne GNSS observations during a 20‐day experiment in 2016 in Fram Strait, the region of the Arctic Ocean between Greenland and Svalbard. The shipborne GNSS PWV shows an agreement of ~1.1 mm with numerical weather model data and radiosonde observations, and a root‐mean‐square of ~1.7 mm compared to Satellite with ARgos and ALtiKa PWV. An improvement of 10% is demonstrated with the multi‐GNSS compared to the Global Positioning System solution. The PWV retrieval was conducted under different sea state from calm water up to gale. Such shipborne GNSS PWV has the promising potential to improve numerical weather forecasts and satellite altimetry

Defence and the Arctic : go with the floe?

Article published in the RUSI Journal, Volume 154, Issue 4 August 2009 , pages 82-86As the Arctic ice melts, the polar region is becoming increasingly exposed to the political tussles of resource exploitation. Accompanying the territorial disputes is the imminent militarisation of the international space by circumpolar states. The UK has a difficult decision to make: either include the Arctic in its future defence strategy or advocate a zone of peace in this valuable part of the world. it cannot do both
