Urban ecosystems and green spaces are paramount to the mental well-being of communities. Lakes and ponds in particular provide a critical venue for recreational opportunities from swimming and fishing in the summer, to ice-skating in the winter, and in some cases provided drinking water to local communities. Because of their proximity to residential and industrial developments, urban ponds are also vulnerable to local sources of pollution such as road and lawn runoff and factory effluent. No pond typifies both the importance and vulnerability of urban ponds better than Providence’s Mashapaug Pond. Continue reading
Well, classes are wrapping up at Brown and my official duties as Limnology TA are done. But my unofficial duties aren’t complete until I get some more awesome limno field trip pictures online. The class does two trips to Pout Pond (Belmont, NH) each year. The first trip is in winter (see previous post), and the second trip, shown here, is in spring.
Hi. I hope that my abundance of field-work related pictures does not lead you to believe this is all I do. The vast majority of my time is spent in the lab or on the computer analyzing samples and data, and making figures and writing. These are all very exciting things to do. None-the-less, I am sharing more field work pictures because they are prettier. Two field projects I helped with this spring involved sediment coring in Rhode Island. Continue reading
Hello blogosphere! Happy 2016!! We survived winter and the geology field season is ramping back up in the northern hemisphere. To kick off the 2016 fieldwork campaign I went with Brown University’s Limnology class, taught by Jim Russell, on a field trip to New Hampshire. The goal of the class is for students to become familiar with and proficient in all things related to lakes, and this includes field sampling. Six students, Jim, and I went to Pout Pond, near the town of Belmont, NH to take water measurements and samples. Students measured lake temperature, pH, dissolved oxygen, conductivity, alkalinity, and secchi depth, and took water samples to measure salts and nutrients.
Here are some pictures from the beautiful day.
I recently moved into a house on Transit St. in Providence. Legend has it that the house was built by the aunt of composer George Cohan (this was a big selling point for me, no doubt). But, that is only kind of cool in comparison to the etymology of the street name itself. Transit Street was so named because in the 18th century, it was considered one of the prime locations in the world to view the Transit of Venus (the passage of Venus between Earth and the sun) and astronomers from New England gathered there to watch the event in 1769.
The pictures below are not the Transit of Venus, but they do represent a planetary transit that I captured earlier this fall. It is the blood moon – a combination supermoon and complete lunar eclipse. I took pictures at 30x optical zoom with my Nikon point-and-shoot camera mounted on a tripod. I was pleased with the outcome from such a small camera. Enjoy.
This blog is about the Kaktovik Oceanography Program and the wonderful experience I had volunteering with the program in 2015. The KOP is an annual week-long natural science camp for local students in the town of Kaktovik, Alaska. It is hosted by the US Fish and Wildlife Service (thanks Greta Burkhart and Allyssa Morris), and largely coordinated by Ken Dunton’s research group from University of Texas. Students spend the week thinking about ecosystems, evolution, geology, etc., and do a lot of hands-on field work in the local lagoons and coastal habitats. Our goal was to show the participants that doing science is not only important and interesting, but also fun and a potentially viable career path. Continue reading
Today Brown geology grads, undergrads, and postdocs celebrated our third successful season with the URI Watershed Watch program. The WW, coordinated by the URI cooperative extension, monitors about 120 RI water bodies on a weekly basis from May to October, all through the volunteer efforts of RI citizens. The long-term data (>20 years for some lakes) are used to assess restoration efforts, pollution impacts, climate change impacts, etc. Full information can be found at the URI-WW website.
