Ecosystem processes and functioning across current and future dryness gradients in arid and semi-arid lands
02 Aug 2016–30 Jun 2017 | Guest editors: T. Zha, C. Bourque, Z. Xing, S. Luyssaert, and P. Stoy | Information


Ecosystems in arid and semi-arid regions of the world are frequently affected by periods of extended drought and resource over-exploitation. Dryland ecosystems are particularly sensitive to climate change in terms of plant species associations, plant distribution along environmental gradients, ecosystem functioning, and ecological and economic productivity. Environmental change in these areas may require that new management strategies and field approaches be developed to protect these vulnerable ecosystems. A devoted account of dryland ecosystems and their response to changing environmental conditions can help develop new management strategies and inform policy.

To facilitate the study of arid and semi-arid ecosystems and provide recent research findings in the area, we propose that the special issue address the following:

  • characterizations of vegetation growth patterns and productivity along dryness gradients in China and in other areas of the world,
  • assessments of dryland ecosystems with combating global warming and in contributing to the uptake and storage of greenhouse gases,
  • systematic studies of desertification and related land degradation processes,
  • assessments of resiliency and hydrological responses of dryland ecosystems to climate change, and
  • identification and substantiation of scientifically based management strategies suitable for arid and semi-arid regions of China and other areas of the world.

Progress in quantifying ocean biogeochemistry – in honour of Ernst Maier-Reimer
01 Jul 2016–30 Jun 2017 | Guest editors: C. Heinze, T. Ilyina, A. Winguth, J. Segschneider, and M. Hofmann | Information


Ernst Maier-Reimer was one of the pioneers in global modelling of ocean biogeochemical cycles and especially the carbon cycle. He published – together with Klaus Hasselmann – the first comprehensive paper on anthropogenic carbon uptake by the ocean. He provided extensive models on both the inorganic as well as the organic carbon cycle in the ocean. His models were elegant in their mathematical formulation, efficient, and computationally economic. He was very influential in this field through the sharing of his knowledge. A number of state-of-the-art biogeochemical ocean model components in Earth system models can be traced back to him and his modelling philosophy. His ability to separate important processes from unimportant provided a role model for geoscientific modellers. Ernst implemented numerous different tracers into his ocean models and took advantage of considering all in a synoptic view of constraining the overall biogeochemical action of the world ocean. This special issue is open for submissions from everyone who knew Ernst, learned from him, or collaborate with him. It should be a celebration of classical and new topics in quantitative biogeochemistry with key papers aimed at understanding the ocean as a chemical plant.

NETCARE (Network on Aerosols and Climate: Addressing Key Uncertainties in Remote Canadian Environments)
(ACP/AMT/BG inter-journal SI)

23 Feb 2016–28 Feb 2019 | Guest editors: L. Bopp, K. Carslaw, D. J. Cziczo, and L. M. Russell | Information


NETCARE (Network on Aerosols and Climate: Addressing Key Uncertainties in Remote Canadian Environments) is a large research network focusing on aerosol–cloud–climate interactions. While Canadian-based, it operates with many international collaborations. It is comprised of scientists working in both atmospheric science and marine biogeochemistry, with particular attention given to a suite of intensive field measurements (with both atmospheric and oceanic components) and model evaluation and development. There are three major research directions within the network: 1. Carbonaceous Aerosol, 2. Arctic Clouds, and 3. Ocean–Atmosphere Interactions. A large amount of the research has an Arctic focus, it being a region especially susceptible to anthropogenic input and experiencing a large degree of biogeochemical change. The website for the network is www.netcare-project.ca. On the website, there is more information on research activities, field campaign details, modeling activities, data products, and personnel.

Changing Permafrost in the Arctic and its Global Effects in the 21st Century (PAGE21) (BG/TC/GMD/ESSD inter-journal SI)
01 Jan 2016–31 Jul 2017 | Guest editors: K. Thonike, V. Brovkin, P. Stoy, S. Natali, I. Laurion, and B. Elberling | Information


Permafrost is defined as ground that remains continuously at or below 0°C for at least two consecutive years; some 24% of the land surface in the Northern Hemisphere is classified as permafrost. In the northern high latitudes, strong warming has been observed over the recent decades, and climate models project strong future warming. A projected decline in the extent of permafrost will have a major impact on the Earth system, affecting global climate through the mobilization of carbon and nitrogen stored in permafrost. This special issue invites results of the large-scale European project PAGE21 with the aim to quantify the vulnerability of permafrost environments to a changing global climate, and to investigate the feedback mechanisms associated with increasing greenhouse gas emissions from permafrost zones. The focus is on (i) the combination of field mapping and measurements of permafrost landforms, ground ice content, processes, pools, and fluxes, with remote sensing data and global climate models at local, regional, and pan-Arctic scales, as well as (ii) advancing our understanding of permafrost processes at multiple scales, resulting in improvements in global numerical permafrost modeling.

Climate–carbon–cryosphere interactions in the East Siberian Arctic Ocean: past, present and future
(TC/BG/CP/OS inter-journal SI)

01 Oct 2015–31 Mar 2017 | Guest editors: Ö. Gustafsson, J. Middelburg, and F. Peterse | Information


This special issue, spanning different Copernicus journals, tallies the current understanding of the cryosphere–carbon–climate (CCC) interactions in the East Siberian Arctic Ocean (ESAO) and related areas.

The ESAO is the largest shelf sea system of the World Ocean. It is perennially ice-covered, receives inflow from large rivers, hosts most of the Arctic subsea permafrost and shallow gas hydrates, and is one of the areas that have been experiencing the largest warming in recent decades. Despite its importance to a wide range of geoscience issues, this system has historically been only sparsely investigated. There has however been a number of major expeditions to the region in recent years, including the 90-day icebreaker-based SWERUS-C3 expedition in summer 2014. The current interest in the past, present and future functioning of this system makes it ripe for a major special issue.

Carbon/methane from this area may be remobilized and interact with large-scale biogeochemical cycles and the climate. The history of the ESAO cryosphere also includes the question of Pleistocene ice sheet extents, and the region has experienced one of the largest summer sea ice reductions in the Arctic Ocean during the last decades, with implications for ocean and atmospheric circulation, air–sea interactions and marine life, as well as erosional release of coastal permafrost carbon and sediment dynamics. Stimulated by recent field campaigns such as SWERUS-C3, submissions will be encouraged from all known programmes, spanning from deep geology, via permafrost carbon release and land–shelf–basin interactions, to palaeoglaciology, as well as a wide range of ocean and atmosphere processes. The aim of the special issues is to provide a well-contained collection of improved understanding of the ESAO-CCC interactions from geological timescales to contemporary processes to projections of future trajectories.

The special issue is open for all submissions within its scope (contingent on the chief editor's decision).

Observations and Modeling of the Green Ocean Amazon (GoAmazon2014/5) (ACP/BG/AMT/GMD/GI inter-journal SI)
01 Jun 2015–31 May 2018 | Guest editor: J. Schöngart | Information


Observations and modelling of the Green Ocean Amazon (GoAmazon2014/5): the GoAmazon2014/5 campaign sought to quantify and understand how aerosol and cloud life cycles in a particularly clean background in the tropics were influenced by pollutant outflow from a large tropical city. The project addressed the susceptibility of cloud–aerosol–precipitation interactions to present-day and future pollution in the tropics. The experiment took place in central Amazonia from 1 January 2014 to 31 December 2015, including intensive operating periods and aircraft in the wet and dry seasons of 2014.
