Effects of climate change on advective fluxes in high latitude regions, May, 2012

IMBER workshop sponsored by ESSAS and ICED on "Effects of climate change on advective fluxes in high latitude regions" (W4, 14 May 2012)

Convenors:
Ken Drinkwater (Institute of marine Research, Norway)
George Hunt (University of Washington, USA)
Eugene Murphy (British Antarctic Survey, UK)
Jinping Zhao (Ocean University of China, PR China)

This 1-day workshop will briefly review the advection of water masses within and between polar and sub-polar regions and their driving mechanisms. It will also review the role of advection on the ecology of these high latitude regions, including heat and nutrient fluxes as well as the advection of flora and fauna (Click here for more details about workshop's background). The major objective of the workshop, however, is to develop likely scenarios of these advective fluxes under climate change. Comparative studies of the responses in the Arctic and Antarctic regions are also of interest. To achieve these objectives we plan to bring together atmospheric scientists, climatologists, biogeochemists, physical and biological oceanographers, ecologists, and fisheries scientists who will use a combination of conceptual, statistical and numerical models studies. The workshop will also receive input from the ESSAS-sponsored Theme Session on “Arctic-Subarctic Interaction” to be held at the Ocean Sciences Meeting in Salt Lake City in February 2012 and the ICED Sentinel meeting on “Southern Ocean Ecosystem Change and Future Projections” to be held in Hobart in early May 2012. The workshop will consist of a few focused invited talks with significant discussion time to address the main topic, the expected future high latitude circulation patterns and their ecological effects.

The primary outcomes of the workshop aim to be:

1. a paper on the future physical, chemical and biological fluxes in high latitude regions under climate change;
2. identification of the gaps in our knowledge about these advective processes and development of recommendations for future research to address these gaps;
3. discussions on the formation of a Working Group under IMBER to compare the structure and function of sub-polar and polar ecosystems for the Arctic and Antarctic.

World Oceans Summit, Cepella, Singapore

The world’s oceans are the setting for increasing economic activity and will continue to be so for years to come. Only in recent years have scientists begun to understand the significant impact of this growing industrialisation on the ecosystems of the seas and, by extension, on the broader biosphere we all inhabit. Now is the time to engage the global business community and change the nature of the debate...

POGO-SCOR Visiting Fellowships

This programme is jointly funded by POGO and the Scientific Committee on Oceanic Research (SCOR) and is designed to promote training and capacity building leading towards a global observation scheme for the oceans. The Programme has been a success for ten years, with a total of 125 fellowships awarded since 2001.  The fellowship program is open to scientists, technicians, graduate students (PhD) and post-doctoral fellows involved in oceanographic work at centres in developing countries and countries with economies in transition. Its main purpose is to advance sustained ocean observations and their applications.  Priority is given to applicants in early stages of career development. The fellowship is not intended for pure, "blue skies" research; it offers the opportunity to visit other oceanographic centres for a short period (1 to 3 months) for training on any aspect of oceanographic observations, analyses, and interpretation.

The Selection Criteria involve a number of factors including:

1. Quality of the application;
2. Relevance of the application to the priority areas identified in the Fellowship Announcement (Argo Floats; Fixed-Point Time-Series Observations; Large-scale, Operational Biological Observations including Biodiversity; Emerging Technologies for Ocean Observations; Data management; Coastal observations/ Coastal Zone Management; Ocean and coastal modelling)
3. Evidence that the training will lead to capacity-building with potential lasting impact on regional observations; and,
4. The need to maximise regional distribution of the awards....

POGO Visiting Professorship Programme

Introduction

In collaboration with the Nippon foundation, POGO established the NF-POGO Visiting Professorship Programme, which ran for 3 years (2004-2007). This initiative metamorphosed into the Centre of Excellence Programme, which allows scholars from developing countries to receive training from world-class scientists for ten months at the Bermuda Institute of Ocean Sciences.

POGO continues to run a Visiting Professorship programme, which generally funds one Professor every year. The Professorship allows short visits (2 weeks to 3 months) of distinguished scientists from advanced oceanographic institutes to institutes in developing countries and economies in transition, to provide training and mentoring, to develop collaborations and enhance networking. Follow this link to read about past POGO Visiting Professorships.

The goal of the visiting professorship is capacity building in the host institution, leading to enhanced sustained ocean observations to address societal issues of the day. Development of highly-trained scientific professionals is the priority. Promoting contacts, collaborations and networking among institutions of developing and developed countries is another goal.

This programme is seen as a complement to the POGO-SCOR Visiting Fellowship Programme.

Explanation for glowing seas suggested

Proposed bioluminescence mechanism: When a dinoflagellate is mechanically agitated, an electrical impulse travels around its vacuole membrane. This impulse opens up proton channels that allow protons to flow from the vacuole into the scintillons, where they activate light-emitting luciferase proteins. The result: A flash of light. Credit: Zina Deretsky, National Science Foundation

It has long been known that distinctive blue flashes -- a type of bioluminescence -- that are visible at night in some marine environments are caused by tiny, unicellular plankton known as dinoflagellates. However, a new study has, for the first time, detailed the potential mechanism for this bioluminesence.

The study, which was partially funded by the National Science Foundation, is reported by Susan Smith of Emery School of Medicine, Thomas DeCoursey of Harvard University and colleagues in the Oct. 17, 2011 issue of the Proceedings of the National Academy of Sciences (PNAS).
A key aspect of the potential mechanism for bioluminescence in dinoflagellates proposed in the PNAS study involves voltage-gated proton channels--channels in membranes that can be opened or closed by chemical or electrical events.
J. Woodland Hastings, a member of the Smith and DeCoursey research team and an author of the PNAS article, suggested the presence of voltage-gated proton channels in dinoflagellates almost forty years ago. But the Smith and Decoursey team only recently confirmed them by the identification and subsequent testing of dinoflagellate genes that are similar to genes for voltage-gated proton channels that had previously been identified in humans, mice and sea squirts.
According to the study, here is how the light-generating process in dinoflagellates may work: As dinoflagellates float, mechanical stimulation generated by the movement of surrounding water sends electrical impulses around an internal compartment within the organism, called a vacuole--which holds an abundance of protons. (See accompanying illustration.) These electrical impulses open so-called voltage-sensitive proton channels that connect the vacuole to tiny pockets dotting the vacuole membrane, known as scintillons.
Once opened, the voltage-sensitive proton channels may funnel protons from the vacuole into the scintillons. Protons entering the scintillons then activate luciferase--a protein, which produces flashes of light, that is stored in scintillons. Flashes of light produced by resulting luciferase activation would be most visible during blooms of dinoflagellates.
This research illuminates the novel mechanisms underlying a beautiful natural phenomenon in our oceans, and enhances our understanding of dinoflagellates--some of which can produce toxins that are harmful to the environment.

No simultaneous warming of Northern and Southern hemispheres as a result of climate change for 20,000 years

Svante Björck's study thus goes 14 000 years further back in time than previous studies have done.
"What is happening today is unique from a historical geological perspective", he says.
Svante Björck has gone through the global climate archives, which are presented in a large number of research publications, and looked for evidence that any of the climate events that have occurred since the end of the last Ice Age 20 000 years ago could have generated similar effects on both the northern and southern hemispheres simultaneously.
It has not, however, been possible to verify this. Instead, he has found that when, for example, the temperature rises in one hemisphere, it falls or remains unchanged in the other.
"My study shows that, apart from the larger-scale developments, such as the general change into warm periods and ice ages, climate change has previously only produced similar effects on local or regional level", says Svante Björck.
As an example, let us take the last clear climate change, which took place between the years 1600 and 1900 and which many know as the Little Ice Age. Europe experienced some of its coldest centuries. While the extreme cold had serious consequences for agriculture, state economies and transport in the north, there is no evidence of corresponding simultaneous temperature changes and effects in the southern hemisphere.
The climate archives, in the form of core samples taken from marine and lake sediments and glacier ice, serve as a record of how temperature, precipitation and concentration of atmospheric gases and particles have varied over the course of history, and are full of similar examples.
Instead it is during 'calmer' climatic periods, when the climate system is influenced by external processes, that the researchers can see that the climate signals in the archives show similar trends in both the northern and southern hemispheres.
"This could be, for example, at the time of a meteorite crash, when an asteroid hits the earth or after a violent volcanic eruption when ash is spread across the globe. In these cases we can see similar effects around the world simultaneously", says Svante Björck.
Professor Björck draws parallels to today's situation. The levels of greenhouse gases in the atmosphere are currently changing very rapidly. At the same time, global warming is occurring.
"As long as we don't find any evidence for earlier climate changes leading to similar simultaneous effects on a global scale, we must see today's global warming as an exception caused by human influence on the earth's carbon cycle", says Svante Björck, continuing:
"this is a good example of how geological knowledge can be used to understand our world. It offers perspectives on how the earth functions without our direct influence and thus how and to what extent human activity affects the system."
Svante Björck's results were published this summer in the scientific journal Climate Research.
