Ocean acidification – how do we respond?

Ocean acidification is progressively affecting the structure and function of entire ecosystems, and is recognised as a threat to the economy particularly shellfish and fisheries sectors. This workshop provides an interactive opportunity for key Scottish stakeholders to learn about potential effects, to collectively consider possible response options and to exchange experience with Norwegian representatives.

“The Global Ocean Acidification Observing Network, GOA-ON: linking local information globally”, 2018 Ocean Sciences Meeting, Portland

Abstracts are due 6 September 2017!

Session Description: The Global Ocean Acidification Observing Network, GOA-ON (www.goa-on.org), was established in 2012 to serve scientific and policy needs by providing coordinated, worldwide information on ocean acidification and its ecological impacts.  The work of GOA-ON is guided by three high level goals: 1) to improve our understanding of global ocean acidification conditions; 2) to improve our understanding of ecosystem response to ocean acidification; and 3) to acquire and exchange the data and knowledge necessary to optimize the modeling of ocean acidification and its impacts. GOA-ON was organized by scientists for international coordination, with researchers from 66 countries now participating, has evolved to incorporate regional hubs for collaboration, and provides and promotes training and capacity building activities. By using consistent methods and networking data, GOA-ON enhances our understanding of the local expressions of this global process, thereby covering a range of spatial scales.

Session 27656: “Ocean global change: teasing apart individual and interactive effects of drivers on microbes and plankton”, Ocean Sciences Meeting, 11-16 February 2018 in Portland, Oregon

Topic Area: Microbiology and Molecular Ecology

Co-convenors:  Uta Passow, Philip Boyd, David Hutchins

Description:

Our changing climate is modifying concurrently many oceanic properties which are biologically influential.  Assessing the cumulative effects of each of these changes on marine biota poses a grand challenge to ocean scientists for several reasons.  First, for microbes and phytoplankton up to six influential, environmental properties are being simultaneously changed. Second, it is being increasingly shown, that there are often subtle interactions between these drivers, and that these interactive affects are frequently non-additive. As a result, the response to simultaneous stresses can’t be predicted from response patterns of each one individually. Third, the effects of ocean global change can be further modified by local and regional drivers.  The wide range of environmental permutations requires careful experimental design to distinguish responses to individual versus interactive stresses. In this session we solicit presentations on conceptual and numerical modelling, novel experimental approaches and manipulation studies that target physiology, omics, microevolution and community responses to multiple perturbations.

Session 29804: “Spatial and Temporal Variability of Seawater Chemistry in Coastal Ecosystems in the Context of Global Change”, Ocean Sciences 2018, 11-16 February 2018, Portland

Session description

Coastal systems provide a range of goods and services that are under threat from anthropogenic stressors such as ocean acidification, deoxygenation, and eutrophication. Accurately projecting future chemical conditions in these socioeconomically important regions remains difficult due to the natural spatiotemporal variability in seawater chemistry. In coastal regions, complex processes including terrestrial-based riverine and groundwater inputs, intense benthic and pelagic metabolism, and air-sea gas exchange act in combination with physical processes affecting mixing, water column depth, and local residence times. These biogeochemical and physical processes interact over timescales of minutes to years and on spatial scales from millimetres to kilometers to drive variability in seawater chemistry.

The complex, local drivers of seawater chemistry in coastal systems make it increasingly difficult to predict how seawater chemistry will change due to anthropogenic changes on a global scale. Importantly, certain oceanographic areas and ecosystems could act as de-oxygenation and acidification refuges by elevating DO and pH relative to source or surrounding waters. For this session we invite contributions seeking to understand temporal and spatial variability of seawater chemistry in coastal systems in the context of global climate change. We also welcome submissions that highlight the effects of seawater chemistry variability on marine organisms and ecosystems.

Recording from the UN Oceans Conference Partnership Dialogue 3 – Minimizing and Addressing Ocean Acidification (text and video)

In the afternoon, the Conference held a partnership dialogue on “Minimizing and addressing ocean acidification”. Moderated by Petteri Taalas, Secretary-General, World Meteorological Organization, it featured presentations by Cardinal Peter Turkson, Head of the Dicastery for Integral Human Development, Holy See; Rahanna Juman, Deputy Director, Institute of Marine Affairs, Trinidad and Tobago; David Osborn, Director of the International Atomic Energy Agency (IAEA) Environment Laboratories; and Carol Turley, Senior Scientist, Plymouth Marine Laboratory, United Kingdom. Prince Albert II of Monaco and Agostinho Mondlane, Minister of the Sea, Inland Waters and Fisheries, Mozambique, co-chaired the meeting.
