While you may not think that rescuing fish from a flood control basin would be interesting, read this release from the DFW regarding the rescue of hundreds of fish near the Sacramento Delta and you might change your mind. With ESA-listed species included, hundreds of salmon, steelhead, and sturgeon were removed from the Fremont and Tisdale Weirs and re-released into the Sacramento River this month.
Making this rescue all the more interesting is that DFW technicians implanted many of the fish with tracking devices to provide scientists with both survival and spawning data. In addition, DNA testing was conducted on the salmon to determine specific seasonal runs. Very Cool. Read the release below.

With Christian McDonald being honored this week by the Los Angeles County Underwater Unit, it’s only appropriate to take a look back at the first DSO at Scripps, Conrad Limbaugh. Pictured below, Connie was truly the innovator in terms of the use of scuba equipment in scientific studies. Starting at UCLA in 1949, Limbaugh moved to SIO in 1950 and started to develop the standardized training that became the basis not only for the scientific dive community but for the entire new burgeoning recreational scuba movement in the United States. Appointed “Dive Safety Specialist” in 1953, Limbaugh spent 7 years at SIO helping change ocean research as we know it. Tragically, he died in a cave diving incident in 1960 at the age of 36. Today, there are multiple awards named for Limbaugh including the Conrad Limbaugh Award for Scientific Diving Leadership by the AAUS. The color picture below was provided from the private collection of Dr. Andreas Rechnitzer, a good friend of Connie’s and an amazing SIO figure in his own right. You can read more about Connie here and Andy here.

Last night, Scripps Scientific Diving Officer Christian McDonald was named an honorary Underwater Instructor by the Los Angeles County Underwater Unit at the programs annual awards dinner for his contributions supporting their Underwater Instructor Certification Course. This program, developed in 1954 by LA County lifeguards participating in the then newly developed SIO scientific diving course, is the worlds oldest public safety program and has certified over 1100 underwater instructors since. Christian joins only 7 other persons, including SIO DSO emeritus James Stewart and SIO graduate Dr. Wheeler J. North, as honorary instructors for the county of Los Angeles. Congratulations Christian.

“The oceans are extremely important, not only to our climate, but to our health and our global ecosystems…. For climate change, they play a central role. About a quarter of carbon emissions that we emit every year end up in the ocean.”
-Yassir Eddebar, PhD candidate, CMBC, Scripps Institution of Oceanography
This year’s United Nations Conference of the Parties in Paris will write a treaty to address climate change. It’s taken decades to get here. UCSD has sent several graduate students to the conference to learn about and participate in the global system of science policy.
Read more about their work this week in their blog on the San Diego Union Tribune.
Watch Yassir on KPBS just before they left for Paris:

What would life be like if you chased truly wild places … for work?
Each year I’m lucky enough to travel for fieldwork. I’m a PhD student here at Scripps, studying coral reef ecology. Each year I make short videos to communicate our work, our lives as a rock stars… I mean scientists… and the truly wild landscapes we briefly call home. This year I focused on the people behind the science. What kind of person takes a job on an (almost) deserted island in the middle of the Pacific Ocean? Do you have what it takes? Would you want to? Below is a teaser trailer for a mini-mini-documentary coming soon. Everyone has their own path to happiness. For some of us, that path is winding, isolated and full of weird hairy spiders. For the love of science, nature, and exploration: Welcome to the Edge of the World.

It is always good to be reminded why I like being a professor, and this was one of those days. Every summer we have lead a CMBC cruise to the offshore waters of San Diego. This year we made two amazing net hauls next to the Coronado Bank. The first was from ~200 m and was full of some 170,000 tuna crabs–the harbingers of el Nino–who have been mass stranding on the beaches of late. Well, now we know where they come from! I felt like I was on a trawler from the days-of-yore before industrial fishing. This haul also had a neat octopus, urchins, fish and spider crabs.
Then came the mid water tow at 550 m, and it was loaded with wonders too–the kind that Hollywood film makers should love and are the stuff of nightmares as you toss and turn in the dawn hours. We caught three kinds of Dragonfish, two species of Hatchet Fish, an angler, a Snipe eel with a whiplike tail, and the most wild of all–a Loose Jaw, that looks like it was mangled, but really has almost nothing holding its jaw in place! These fish reside in a world that is physically not that far from ours (it probably takes 5 minutes to walk 500 m!) but is almost totally different anyway! Majesty! Wonder! Thrills! And Fascination!
What gets me is how alien their world is. These are fish attract their prey with lighted lures, sense their prey by pressure, and make sure they don’t lose their prey by attacking with huge nasty teeth. The hatchet fish have eyes that permanently look upward to spot the faint shadow of prey above them. And most everybody has rows of photophores on their bellies to keep from casting a shadow on some larger fish below them. The photophores are like miniature flood lights, complete with a black case and a crystalline lens. The world is full of things more bizarre and exciting than most people know. Beat’s landing on the moon any day…It really was one of the great adventures in my life….
Best is to have a crowd of students to share the adventure.

The recent rise in gasoline prices has got a lot of lawmakers looking for ways to bring the prices down for their constituents and it seems the solutions always come back to drilling offshore here in California. Despite a pledge from President Obama to not allow any new drilling off the West Coast, there still remains a uneasy feeling among Pacific range lawmakers. This has led Senators from California, Oregon, and Washington to propose new legislation formalizing the Presidents un-codified pledge. Though it’s not expected to gain much traction in the Republican-controlled house, it’s a shot across the bow that shows West Coasters are serious about there being no new drilling in our local waters. Enjoy a more in-depth article from the LA Times below:

In less than a decades time, Indo-Pacific lionfish have established what appear to be permanent populations along the southeast U.S. coast and into the Caribbean. With population densities in some spots ranging to 1000 fish per acre, these veracious eaters are quickly decimating local fish populations as they start to range towards the Gulf of Mexico and South America. Efforts so far to reign in this dangerous invasive have met with little success but now scientists at NOAA, along with numerous non-profits and local island governments, have come up with a new plan…eat them.
Using a variety of marketing strategies that include cash prizes for most lionfish caught in one year on Grenada, the hope is to turn lionfish into a desirable food-fish with no limits catches being the goal.
The supporters of the effort say that lionfish tastes like grouper or snapper, two highly sought after species. That sounds like good eats to me. If that’s the case, then hopefully this is the recipe that turns the tables on this tropical invasion. I think the effort bears watching and all puns intended, it’s an interesting and unorthodox piece in invasive species puzzle that up until now has challenged fisheries managers. We’ll see.

Recently the LA Times ran an article about the city of Ventura reacting to sea level rise as a result of climate change. With the encroachment of Pacific waters on the local shoreline such as at Surfers Point, Ventura officials have been forced to react by taking out crumbling bike paths and eroding parking lots while offsetting diminishing beaches by laying down sand. In moves that were foreshadowed by the city of San Diego in their 2050 report, California’s coastal communities are being forced to take a serious look at the implications of a potential 2 meter rise of our local waters. To get a more detailed look at some of the serious problems facing our state, I’ve attached below an interview with one of the authors of the 2050 report, Scripps Oceanographer and Meteorologist Dan Cayan. He offers a detailed look at the state-wide scale of the problem and some of the possible ways to overt the most catastrophic impacts.
