Building on the tradition of excellence of the GRC Conference Series, the 2019 GRC on Polar Marine Science "Shedding Light on the Physical, Biogeochemical and Human Dimensions of Connectivity in Changing Polar Seas" will bring together leading investigators to present and discuss cutting edge research on both polar oceans. The unique GRC format, with invited speakers and discussion leaders, provides an avenue for scientists from different fields to brainstorm and create synergy across disciplines. Conference themes are explored in greater detail during the highly dynamic poster sessions. One-minute oral summaries of posters allow presenters to efficiently address the entire group, paving the way for enhanced interactions during the sessions. A GRC "Power Hour" will be held to help address the challenges women face in science and support the professional growth of women in our communities by providing an open forum for discussion and mentoring.

Spatial and temporal connections within polar oceans and between these oceans, adjacent seas, land and the atmosphere are at the heart of variability and change in the Arctic and Southern oceans. Exploring and understanding these connections can provide powerful insights into the past, present and future state of polar marine ecosystems, including the local and regional aspects of ocean circulation, sea ice dynamics, biogeochemical fluxes, biodiversity, harvestable living resources and human well-being. Because the Arctic and Southern oceans are nexuses that collect and redistribute organisms, chemical constituents, freshwater and heat, their transformations are also expected to affect lower-latitude "downstream" ocean areas at a variety of scales. The 12th GRC will emphasize the multiple facets of connectivity through the presentation of new observations and findings, conceptual frameworks and numerical simulations that explore functional relationships between different components of the polar marine system or the linkages between polar oceans and the broader environment.

A Gordon Research Seminar (GRS) will occur the weekend prior to the 2019 Polar GRC to provide a forum for graduate students and postdoctoral scientists to connect with their peers, present their work, and interact with mentors while exploring one of the GRC's themes. The major focus at the 2019 GRS will be on "Linking Marine Science Disciplines to Enhance Our Understanding of Polar Oceans". Partial financial support will be offered in priority to graduate students and postdoctoral fellows attending both the GRC and the preceding GRS.

This GRC will be held in conjunction with the "Polar Marine Science (GRS)" Gordon Research Seminar (GRS). Those interested in attending both meetings must submit an application for the GRS in addition to an application for the GRC. Refer to the associated GRS program page for more information.

The 3rd International Congress on Stratigraphy (STRATI2019) will be held in Milano, Italy, 2-5 July 2019.

Following the first edition of this congress, held in Lisbon (Portugal) in 2013 and the second edition organized in Graz (Austria) in 2015, the third edition of STRATI has been assigned by the International Commission on Stratigraphy (ICS) to Italy, a country with a long historical tradition in Stratigraphy since the 17th century. Some milestones in the history of Stratigraphy were added in Italy by outstanding scientists such as Niels Stensen and Giovanni Arduino. Moreover, a wide variety of extraordinary stratigraphic successions and settings, often preserved in breath-taking natural environments, can be visited in Italy.

The topics of the congress will range from the Precambrian to the Holocene and will include all the stratigraphic techniques. The congress will provide the opportunity to discuss the recent developments in the study of the stratigraphy of the volcanic areas, Antarctic and Arctic sedimentary successions and ice caps, as well as of crystalline rocks. We also invite specialists from georesources exploration and hydrogeology to present their most advanced contributions to subsurface stratigraphy.

As in previous editions, the congress will also host meetings of the ICS and of its Subcommissions to debate topics and problems in updating and improving the geological time scale.

Abstract submission deadline has been extended to 17 March 2019.

The Gordon Research Seminar on Polar Marine Science provides early career scientists with a unique opportunity to further enhance their Gordon Conference experience.

This GRS will be held in conjunction with the "Polar Marine Science" Gordon Research Conference (GRC). Those interested in attending both meetings must submit an application for the GRC in addition to an application for the GRS. Refer to the associated GRC program page for more information.

Abstract:

Atmospheric methane plays a major role in controlling climate and its atmospheric burden has more than doubled since 1850, yet contemporary methane trends (1982-2017) have defied explanation. Methane concentrations stabilized in the early 2000s and began increasing again in 2007. Neither the stabilization nor the recent growth are well understood, as evidenced by multiple competing hypotheses in the literature over the past 2 years. Explanations for the increases and stabilization have invoked changes in tropical wetlands, livestock, fossil fuels, biomass burning, and the methane sink. This talk will address three main questions: 1) "What do we know about sources, sinks, and underlying processes driving observed trends in atmospheric methane?", 2) "How will global methane respond to changes in anthropogenic emissions?", and 3) "What future observations could help resolve changes in the methane budget?"

This talk will draw on results from a recent open-access paper: Turner*, Frankenberg*, & Kort*, PNAS (2019). The paper is available on the PNAS website or at: https://doi.org/10.1073/pnas.1814297116.

Seminar 3 in the Series, From Science to Solutions: The State of the Carbon Cycle, the 2nd State of the Carbon Cycle Report (SOCCR2).

Abstract for first presentation:

Forest ecosystems are the largest terrestrial carbon sink on earth and their management has been recognized as a relatively cost-effective strategy for offsetting greenhouse gas emissions. In North America, forests, including urban forests, woodlands and the products obtained from them, play a major role in the carbon cycle. In this presentation we examine recent trends, drivers, and projections of U.S. and North American carbon cycle processes, stocks, and flows in the context of interactions with global scale budgets and climate change impacts in managed and unmanaged forest ecosystems. We will also highlight carbon management science and tools for informing decisions and opportunities for improving carbon measurements, observations, and projections in forests.

Abstract for second presentation:

Because carbon (C) density of terrestrial wetlands is much greater than that of upland ecosystems, consideration of C stocks and fluxes along with associated changes resulting from management or land-use change are of particular importance at local, regional and global scales. Through new analyses of recent available data bases and literature, C stocks, net ecosystem exchange (NEE) and methane (CH4) fluxes were estimated for North American (US, Canada, Mexico and Puerto Rico) terrestrial wetlands. North America contains approximately 2.2 million km2 of terrestrial wetlands (approximately 37% of the global wetland area) with anecosystem C pool of approximately 161 Pg (approximately 36% of global wetland C stock). Canada has the greatest area of terrestrial wetlands (52%), followed by the US (47%), Mexico (1%) and Puerto Rico. Likewise, Canada has the largest C stocks, NEE, and CH4 fluxes (80%, 51%, and 57%, respectfully) followed by the US (19%, 43%, and 39%, respectfully) and Mexico (1%, 7%, and 4%, respectfully). Forested wetlands comprise 55% of the total terrestrial wetland area, with the vast majority occurring in Canada. Organic-soil wetlands comprise 58% of the total terrestrial wetland area and contain 80% of the C stock. Overall, North American terrestrial wetlands currently are a CO2 sink (i.e., negative NEE) of approximately 126 Tg of C per year. However, North American terrestrial wetlands are a natural source of CH4, with mineral-soil wetlands emitting 56% and non-forested wetlands emitting 55% of the estimated total of 45 Tg CH4 �"C per year.

The International Glaciological Society will hold an International Symposium on ‘Five Decades of Radioglaciology’. The symposium will be held at Stanford University in Stanford, California, USA on 8–12 June 2019.

THEME:

Radio echo sounding is a powerful geophysical approach for directly characterizing the subsurface conditions of terrestrial and planetary ice masses at the local, regional and global scales. As a result, a wide array of orbital, airborne, towed and in situ instruments, platforms and data analysis approaches for radar sounding have been developed, applied or proposed. Terrestrially, airborne radar sounding data has been used in glaciology to observe ice thickness, basal topography, englacial layers and for more than five decades. More recently, it has also been exploited to estimate the extent and configuration of subglacial water, the ice sheet surface, the geometry of subglacial bedforms, the spatial variation of melt, temperature, and the transition between frozen and thawed bed. Planetary radar sounders have been used or are planned to observe the subsurface
and near-surface conditions of Mars, Earth’s Moon, comets and the icy moons of Jupiter. These instruments provide critical subsurface context for surface sensing, particle, and potential-field instruments in planetary exploration payloads. This symposium will discuss advances in radar sounding systems, mission concepts, signal processing, data analysis, modeling and scientific interpretation.

SUGGESTED TOPICS:

We seek papers and presentations that advance the understanding of radar sounding and its use in physical glaciology. Key focus areas include (but are not limited to):

1. Radar systems: development, performance and platforms
2. Data: intercomparison, validation and release
3. Radar processing: propagation, inversion and automation
4. Englacial structure: layers, deformation and accretion bodies
5. Attenuation: near surface properties, temperature and chemistry
6. Bed conditions: topography, roughness, thermal state and hydrology
7. Interpretation: comparing observations with modeling and theory.

PROGRAM:

True to tradition, the symposium will include oral and poster sessions interlaced with ample free time to facilitate interactions between the participants. Additional activities include an opening icebreaker, a banquet dinner and an excursion during the mid-symposium afternoon break.

ABSTRACT AND PAPER PUBLICATION:

Participants who wish to present a paper (oral or poster) at the Symposium will be required to submit an abstract by 11 March 2019. Accepted abstracts will be posted on the Symposium’s website. The Council of the International Glaciological Society will publish a thematic issue of the Annals of Glaciology on topics consistent with the Symposium themes. Participants are encouraged to submit manuscripts for this Annals volume. The deadline for submission of Annals papers is 1 August 2019.
