The following special issues are scheduled for publication in OS and its discussion forum OSD:
REP14-MED: A Glider Fleet Experiment in a Limited Marine Area
16 May 2016–16 Dec 2017 | Guest editors: G. Nurser, J. Chiggiato, K. J. Heywood, G. Quattrocchi, R. Onken, and A. Russo | Information
The REP14-MED experiment was conducted by the Centre of Maritime Research and Experimentation (CMRE, La Spezia, Italy), and supported by 20 partners from six different nations, offshore from Sardinia. In a limited area of about 110x110 km2, dense oceanographic observations were collected in the period 7–24 June 2014 by two research vessels, eleven underwater gliders from three different manufacturers, various oceanographic and meteorological moorings, surface drifters, and a profiling float.
The main objective of the experiment was the collection of adequate data sets in order to pursue several objectives, including (i) finding the best sampling strategy for ocean forecasting, (ii) model validation, (iii) evaluation of forecast skill, (iv) exploring ocean variability, (v) performing a cost–benefit analysis of glider data collection, and (vi) analysis of mesoscale and submesoscale structures.
This special issue includes invited papers, but it is also open for additional contributions if coherent (to be evaluated by the editors) with the objectives as specified.
Surface Ocean Aerosol Production (SOAP) (ACP/OS inter-journal SI)
01 Jul 2013–31 Jul 2017 | Guest editors: C. Law, M. Harvey, M. Smith, P. Quinn, N. Harris, and M. Hoppema | Information
Biologically-active regions of the surface ocean support production of a range of compounds that influence aerosol particle production, composition and properties in the overlying marine boundary layer. In February-March 2012 the SOAP (Surface Ocean Aerosol Production) voyage examined biotic influences on aerosol production to the east of New Zealand, by targeting phytoplankton blooms along the Sub-Tropical Front, with the aim of constraining the relationships between DMS and aerosol flux and characteristics, and phytoplankton biomass and community composition, by multi-disciplinary research within three workpackages:
The results of this research voyage will be detailed in this Special Issue, which will contain invited papers only.
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: L. Anderson, T. Tesi, and M. Hoppema | 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).
