Dave Helweg and Christian Giardina organized a field trip on the Big Island of Hawai'i immediately following our workshop on Oahu. When the plane that Simon Costanzo and I were on landed in Hilo, Christian contacted us to inform me that his wife, Ingrid Dockersmith, had sailed with me aboard the R/V Westward as part of Sea Semester. I was the Chief Scientist and Ingrid was an Assistant Scientist when we left from Maine and sailed to Barbados, Bequia and eventually St.

I enjoyed the University of Hawaii campus. We used the food trucks for lunch on the first day, and ate at the campus food court on the second day. After the first day of the workshop, we enjoyed sitting outside at the campus pub, drinking local Kona Longboard beer and listening to the mynah birds in the trees. The sound of the mynahs and the sight of pandanus trees made me recall my stint at the University of Queensland.

On 7-8 March, Simon Costanzo and I facilitated an ecodrought workshop at the University of Hawaii at the main campus in Manoa, a suburb of Honolulu. Our host was the Pacific Islands Climate Science Center, headed by Dave Helweg. This Climate Science Center has a huge swath of territory to cover, including American Samoa, the Marshall Islands, Guam, Palau and a host of isolated atolls (e.g., Johnstone, Palmyra).

Talking about Transdisciplinary research in Paris

I attended a 'Transdisciplinary Research Meeting', sponsored by the International Council for Science (ICSU), which is part of UNESCO, and is based in Paris. The meeting was at the ICSU facility near the Arc de Triomphe. Our local host was Vivi Stavrou, from the International Social Science Council (ISSC). Participants came from four continents (North and South America, Europe and Africa), and they all had a keen interest in transdisciplinary research. The following people attended the meeting:

On the trail of iconic Parisian scientists

Following a three day meeting on transdisciplinary research, I had a day to explore Paris in search of the trails of three of my scientific icons. My eighteenth century science icon from Paris is Antoine-Laurent de Lavoisier (1743-1794); my nineteenth century icon is Louis Pasteur (1822-1895); and my twentieth century icon is Marie Curie (1867-1934). Lavoisier:

Following a three-day workshop on transdisciplinary research training, held 15-17 Feb 2017 in Paris, France, I reflected on the essential elements of transdisciplinary research. We spent much of our three days talking about what constitutes transdisciplinary research, and many concepts were discussed. This blog attempts to distill some of this discussion and to put forward a version of what constitutes transdisciplinary research.

Simon Costanzo, Brianne Walsh and I traveled to Boise, Idaho for a second workshop with scientists from the Pacific Northwest Climate Science Center. Our first workshop, held in Portland, Oregon, focused on the issues west of the Cascades, and this second workshop focused on issues east of the Cascades. We heard about the three 'W's (wounded wetlands and water rights), the three 'F's (forests, fires and fish) and the three 'A's (acclimation, adaptation and assemblages).

A new paper on Chesapeake Bay Submerged Aquatic Vegetation (SAV) was published last week by colleagues from the Virginia Institute of the Marine Science (VIMS) and University of Maryland Center for Environmental Science, led by Jon Lefcheck (VIMS). This paper, entitled "Multiple stressors threaten the imperiled coastal foundation species eelgrass (Zostera marina) in Chesapeake Bay, USA" was published in Global Change Biology.

We recently completed our third SAV SYN workshop, which is an effort to synthesize (SYN) data related to the submerged aquatic vegetation (SAV) of Chesapeake Bay. We have been analyzing a variety of data sets to better understand how SAV are responding to changes in the Bay and to understand what we can infer about the progress of Bay restoration activities. This effort is proving to be a productive collaboration among 15 scientists from 5 different institutions.
