Lecture topics for week #10 included streams & rivers as well as the oceans, so it was a water-rich topic choice.
- ocean acidification was chosen by one student
- EPA-mandated clean-up of water flowing into the Chesapeake Bay is not appreciated by PA communities (weirdly enough, link is to the TV station where I used to live in Johnstown, PA before moving to Gustavus)
- we had a discussion in class about why rivers don’t make great political borders and Kristen went out and found an article about a conflict (with guns!) between Costa Rica & Nicaragua because a stream migrated over time–really nice job
- flooding in Sri Lanka, in Haiti (leading to cholera), in Gauteng (South Africa), and in Nova Scotia
- a 360 Myr old shrimp found in Oklahoma (sometimes I wonder how they find these things…but I’m sure one of the paleo blogs covered it–I just don’t tend to follow them!)
- the other paleo story of the week was about dinosaur embryos found in various collections that had been collected 30+ years ago
- on the movie-tie in side, the groundwater chromium plume that inspired Erin Brockovich to take a stand has now spread further out (2nd tie-in this week I saw, since I also read an article today about Jill Tarter — inspiration for Contact — and the REUs that are connected with the SETI project)
- earthquakes: 5.6 in Puerto Rico on 13. November (which news sources are quick to assure readers is NOT an aftershock of the Haiti event), a 2.5 magnitude event in Texas, a 5.1 & 5.2 in Indonesia to welcome Obama, a 4.8 event in Rajasmand (India), and a 2.8 earthquake in Missouri
- the eruption of Mt. Bulusan in Indonesia (also covered by Erik at Eruptions – the Volcanism Blog seems to be on vacation at the moment…)
- Mt Merapi’s continued eruption was just too much of a lure for the majority of the students (love the title of this one: Dangerously hot air: A capricious volcano, but fears ease of another Pompeii from the Economist which also has some sketchy causes for volcanism vs. plate tectonics [DOWNGOING PLATES RARELY MELT–pet peeve])
In case you were curious, this week had 59 entries submitted.
