On April 23 we hosted 100 4th graders from Los Medanos Elementary school in Pittsburg to the Dutch Slough field site. We say a dead beaver, osprey, great blue heron etc. Thanks to Tyler Anthony from CARB, Molly Ferril and Kate Bandy from DWR, the bat expert from UC Davis. as well as Daphne, Kyle and Robert from the Biomet lab. It was lots of fun, great group of kids. It was a beautiful day, the students were engaged and curious.

We hosted our 3rd annual field trip to Dutch Slough with Knightsen and Old River Elementary schools. It was a cold and rainy day. We thank our partners for helping mentor the students. Dylan Chapple from the Delta Council, Molly Ferrill from DWR, Tyler Anthony from CARB, Robert Shortt and Daphne Szutu from the Biomet lab and a fish/wildlife expert from Davis..

Despite the rain and cold, the kids were very flexible and seemed to enjoy the experience, as well as attending parents

Prof. Josep Penuelas from Barcelona returns to visit the Biometlab this week, continuing our multi-year series of visits.

Been informed we will have the pleasure of hosting Kuno Kasak as a Fulbright scholar, from Estonia, for a year starting this August. Fantastic timing.

The Wetland team of Patty Oikawa, Robert Shortt, Adina Paytan, Barbara Haya, Chris Gough and Dennis Baldocchi met with a team from Google, including Randy Spock the Carbon Credits and Removals Lead at Google to discuss Coastal Wetland Restoration for Climate Mitigation

We met with the 5th grade science teachers from Knightsen Elementary to plan the upcoming field trip to Dutch Slough on April 4. This will be the third year of hosting this group.

We also had a planning meeting with teachers from Los Medanos Elementary in Pittsburg. they plan to bring about 100 students to the Dutch Slough site in late April

We have 2 undergraduates starting to work in the Biomet lab

Izzie Kaye Wamsteker is working with Daphne and is learning about the PepprMnt model for calculating methane fluxes in the wetland. During spring break Izzie joined us on a field trip to the delta

Gelary Cardenas will start working on measuring greenhouse gas fluxes with our chamber system as part of her Environmental Science Senior thesis.

Ivan Janssens from Univ of Antwerp is on short term visit to Berkeley with Margaret Torn. We got together to discuss fluxes and flux networks. Ivan was on the early team of EuroFlux in the Ceulemans group and mentored my former postdoc Jorge Curiel Yuste.

we also hosted Ivan and his spouse Inge on a tour of our delta field sites. Nice to share ideas on wetlands

Brian Bailey of UC Davis gave a great seminar on his Helios model system that computes turbulence, radiative transfer and mass and energy exchange over 3D canopies. This lecture is the Future of Biometeorology

We plan to install another Arable at Dutch Slough for educational purposes for students at Knightsen Elementary and for colleagues working at Dutch Slough from Davis, DWR, USGS, etc

ddb gave a public lecture on Fog Sunday Feb 25, 2 pm at the Tomales Historical Society

You thought you knew fog? There’s so much more to this phenomenon in nature, myth, and mystery. FOG. Clarifying the cloudy, fuzzy, misty, murky, soupy thing we live with

Research

Troy Magney and his team from UC Davis installed the T SWIFT system to measure SIF at Tonzi Ranch. Great to get this new way of sensing the canopy. Plus Sophie Ruehr of the Keenan lab installed a thermal camera at the site.

We are also adding more point dendrometers from a sensor in Czech Republic

Cove Sturtevant from NEON came to visit. Gave a lab seminar on the power of ANN to extract information on controls of fluxes and to extract response functions.

Cove is former postdoc and wrote much of our matlab processing code. great to see him again and learn.

Nico Bambach from UC Davis gave the biometlab seminar presentation. Nico is expert on evaporation measurements and modeling from almonds and showed us the many comparisons they are making and how almond evaporation is varying over the year. It uses up to 10 mm/d during the growing season.

ddb was an external reviewer of UCLA's Institute of the Environment and Sustainability, a similar unit at our partner campus. Also met lots of people and students. Very interesting exercise to do. One learns more about the nuts and bolts of how a University Unit functions and a chance to think about where we in the environmental sciences should be going.
