Call for Papers for “Atmosphere-ice-ocean-ecosystem processes in a thinner Arctic sea ice regime: the Norwegian young sea ICE cruise 2015 (N-ICE2015)”

Submission acceptance begins: 1 April 2016
Submission deadline: 30 September 2016

The sea ice in the Arctic Ocean has been in rapid decline, and the largely perennial ice cover a decade ago has shifted to a ice pack composed mainly of thinner and younger ice, that is more vulnerable to melt during summer and with larger open water extents in recent summers. The conseques of ice loss may be felt far away from the Arctic, notwithstanding the local effects on the interactions between ice-ocean-atmosphere and effects on the Arctic marine ecosystem.

This special section will compile the major results from the half-year N-ICE2015 campaign that took place in winter-spring 2015 in the Arctic ice pack north of Svalbard in JGR-Oceans, JGR-Atmospheres and JGR-Biogeosciences. We especially seek for contributions that takes a holistic approach to understand the interactions between hydrosphere-cryosphere-biosphere and potential effects of ice thinning on all components of the system. We also welcome contributions that make use of data collected during the campaign, and that contribute to a better understanding of the conditions in the study region in pan-Arctic, hemispheric, global and climatological context during the campaign.

Call for Papers for “Oceanic Responses and Feedbacks to Tropical Cyclones”

Submission acceptance begins: 1 March 2016
Submission deadline: 31 January 2017

Tropical cyclones (TC) are the most intensive atmospheric process and they cause tremendous disasters to heavy-populated nations, such as China and the US, every year. A better understanding, simulation, and forecast of TC are always a topic of obvious scientific and social importance. It is well known that the ocean has pronounced responses to TC. However, the detailed processes and physical mechanism during the responses are still a mystery. In addition, the ocean also has a complicated feedback to TC, which can leave clear finger-prints on the intensity, trajectory, and the long-term variability of TC. Therefore, we propose a special issue in JGR-Oceans on the topic of Oceanic Responses and Feedbacks to Tropical Cyclones. All manuscripts about the ocean-TC relationship are welcome, such as, but not limited to, the physical mechanism for the ocean-TC interaction, the ocean-TC interaction in the context of climate change, the data assimilation technics during TC, and the simulation and forecast studies of TC using coupled models.

Call for Papers for “Dense water formations in the North Western Mediterranean: from the physical forcings to the biogeochemical consequences”

Submission acceptance begins: 1 September 2015
Submission deadline: Extended to 31 December 2016

The North Western Mediterranean is a specific region playing a key role for the hydrology and biogeochemistry of the whole basin due to (1) the deep convection that redistribute organic and inorganic matters all over the water column, and (2) the subsequent intense spring bloom that represents the most important biological process of the basin at the origin of carbon exports. The MerMeX, HyMeX and MOOSE components of the MISTRALS program focus on the impact of winter convection on the water cycle, redistribution and stoichiometry of matter, development and succession of biological community over an annual cycle, and their potential evolutions. This special section compiles the major results of an unprecedented intensive and innovative effort of observation and modelling over a full annual cycle from June 2012 to September 2013. Ship-based operations, autonomous platforms (gliders, Bio-Argo floats, mooring lines), remote-sensing and coupled modelling were combined to better characterize and understand the NWM dense water formation phenomena, including the associated physical processes, and the biogeochemical response of the pelagic ecosystem.
