Summer in Moss Landing

July 5, 2013

HFBby Heather Fulton-Bennett, Phycology Lab

Q: What do grad students do during the summer?

A: Thesis! Work! Everything!

We are lucky enough to be at the center of the Monterey Bay, and summers are the perfect time to take advantage of the large marine research community in the area.

This summer I am working as an intern at the Monterey Bay Aquarium Research Institute (MBARI), just across the water from Moss Landing Marine Labs in Moss Landing. MBARI’s research focuses on the development and use of marine technology as well as the exploration and monitoring of the ocean. As an intern there, I am working with Drs. Jim Bellingham and Julio Harvey on correlating optical measurements of zooplankton with molecular methods in the laboratory. These measurements will allow us to have a better understanding of the data sent back from in situ instruments as well as giving a better idea of the effects of confounding factors in both the optical and molecular measurements.

In the few weeks I’ve been here, there have been a lot of familiar faces around MBARI. Several other MLML students are taking advantage of MBARI’s facilities to work on projects related to their these, including a couple of my fellow interns, Vignesh Soundararajan and Diane Wyse, who are working with Francisco Chavez and Jim Bellingham respectively.


R/V Point Sur in Transit

May 1, 2013

The R/V Point Sur is heading home this week, and students have had the opportunity to help with various science operations and add some cruise time to their resumes by joining up for a leg or two of the trip.  Check out this post by Ashley Wheeler, a first year in the Geological Oceanography Lab at MLML, about her experiences aboard our beloved vessel.

Pinnacles National Monument

September 23, 2012

Who would have thought an extinct volcano can be so very multifaceted and interesting? Not me.

Our Geological Oceanography Class at MLML went to the Pinnacles National Monument the other day, driving up this windy road off of Soledad, California, we see this:

Our professor Ivano Aiello asks the question I very much dread, especially when I have absolutely NO CLUE what the answer could be:

” How do you think these peaks formed that you see in the distance?”

Well, let’s get a bit closer… shall we?

What you see here is actually part of the tube that used to lead into the Magma chamber. The volcano is extinct…no more Magma here, but how did it form?

The usual suspects – a fault line, some major earthquake action, you know the Spiel, Bam volcano. Now, the amazing part is that half of the volcano is actually in Southern California as part of the Neenach Volcanics complex, the other up here in Central California. Due to the position of Pinnacles on a fault line it has been transported all the way up north over the period of 30 million years.

Pinnacles features great hiking opportunities, and if you bring a Geologist friend, an amazingly educational hike at that.

Here you see the original side of the volcano. Smoother than the first formations I showed you:

Here’s Ivano explaining one rock formation type at Pinnacles: The Volcanic Breccia, composed of lava flow cementing multiple types of intrusive rocks that originated from the volcano when it was still active.

Make sure to bring plenty of water on your hike. The heat can be quite overwhelming. We found huge relief from the heat in caves that were definitely not caves as you may have experienced before. These caves were formed by piled-up boulders that went through some major events from earthquakes to subsequent lava flowing over them, cooling, and some more earthquakes, and an occasional landslide as well, oh sure, floods, too.

Bring your flashlight!

This was a treat!

Adventures in Madagascar or On The Importance of Doing a Pilot Study!

September 4, 2012

by Angela Szesciorka, Vertebrate Ecology Lab

This summer I hopped on a plane, flying 29 hours one way (via Paris — ooh la la) over a period of three days to spend nearly a month on the island of Madagascar working on my pilot study.

Madagascar, a former French colony until 1960, is the fourth largest island in the world. Don’t let it fool you. It looks so tiny next to Africa, but it has 44 percent more area than California, and boasts more than 4,800 km of coastline.

Most of the country’s export revenue comes from textiles, fish/shellfish, vanilla, and cloves. Newer sources of income include tourism, agriculture, and extracted materials (titanium ore, chromite, coal, iron, cobalt, copper and nickel). Madagascar provides half of the world’s supply of sapphires! But with a GDP of around $20 billion, The Economist rated Madagascar as the worst economy in 2011. Most of Madagascar’s inhabitants are subsistence livers, meaning they live off of what they can grow or catch.

Acidification and Summer Vacation

June 18, 2012

CSUMB/UROC student, Alex Neu, takes a pH reading

By Alex Neu, CSUMB/UROC research assistant

Not too many undergrads can say they have been fortunate enough to do research. Even fewer can say they’ve been a part of research going into their junior year. And just about one can say he’s been able to be a part of a collaborative research project between Moss Landing Marine Laboratories (MLML) and Scripps Institution of Oceanography (SIO). My name’s Alex Neu and I’m that undergrad. I’m heading into my junior year this fall at California State University – Monterey Bay (CSUMB) and have just started a position as a student researcher with CSUMB’s Undergraduate Research Opportunities Center (UROC). This summer MLML graduate student Emily Donham and I are spending our summer researching the effects of climate change on temperate rocky reef communities here in La Jolla as part of a CA Seagrant project funded to co-PI’s Dr. Scott Hamilton (MLML) and Dr. Jennifer Smith (SIO).

Our project includes studying the differential effects of increased CO2 on calcifying and fleshy algal species. Increased dissolved CO2 leads to a decreased pH and is commonly referred to as ocean acidification. Currently we are working with 2 fleshy species that are found here locally. One species is native to southern California and the other is invasive, or has been introduced and is adversely impacting its new habitat. This week marks the half way point in our first round of experimentation and we are all excited to see what kind of results we’ll find at the end of the month. Will one species fair better than the other? What sort of implications could this have for an invasive species’ ability to outcompete a native in a changing ocean environment?

Individual algal specimens being treated in the wetlab of Dr. Jennifer Smith at SIO.

Our day-to-day activities here include monitoring pH levels in each of our samples, taking water samples from randomly chosen jars to monitor carbonate chemistry, and general upkeep of the wetlab and our electronic data recording systems. We have also done some collecting of crustose coralline algae (CCA) for identification and potential use in future experiments. I have even learned how to do herbarium presses, which are a way of preserving algal specimens by flattening and drying them (apparently Plocamium cartilagineum is everyone’s favorite algae to press).

Thanks to UROC, SIO, and MLML for making this research opportunity possible!

The Unseen Elkhorn Slough

May 15, 2012

By Gabriela Navas, Invertebrate Zoology Lab

Every time you find yourself walking along the beautiful Elkhorn Slough, do you admire all you see? I guess we would have a conversation about the birds, crabs, even the occasional fish you may have seen. What about the snails? Oh yes, what about them? They are actually intermediate hosts to unseen residents of the slough, the trematode Cercaria batillariae. Trematodes are also known as flukes, and even though they may have a bad rap in some circles, they merit respect. Their life cycles involve sometimes one or more hosts, specialized to supplying different needs of the trematode. Some trematodes are even known to take over a snail body and mind modifying its behavior in order to get to its next host! Check this out this video on the trematode species Leucochloridium making “SNAIL ZOMBIES”:

Snail Zombies? You may think primitive, but in fact trematodes have recently been shown to show the ability to form caste systems just like your everyday ant or bee. According to Hechinger et al this is the first time this has been shown in flatworms. Check this out:

So, next time we take a stroll around the slough – let’s chat about the unseen, shall we?

Diving into the Deep

May 12, 2012

By Catherine Drake, Invertebrate Zoology Lab

My family and I have been going to the beach since before I could even walk. I’ve been snorkeling, boogie boarding, and building sandcastles for most of my life. But there is one method of enjoying the ocean that, until a couple of weeks ago, I had not yet tried: scuba diving. When I moved up to the central coast to attend MLML almost nine months ago, I knew that I wanted to get my open water diving certification. That way, eventually I could take the research diving course taught by Dr. Diana Steller. Also, I would ideally like to incorporate diving into my thesis, so I wanted to ensure that I could feel comfortable in such a novel environment.

To get your open water certification through PADI (Professional Association of Diving Instructors), you need to go on four dives. So, on Saturday April 14th, we set out for Stillwater Cove in Pebble Beach with all our dive gear and kayaks. I filled up my kayak with my tank, BC, weight belt, and snorkeling gear, clipped it all in and set off into the cove. On Sunday, we got on a boat in Monterey Harbor and set out into the bay. Our first site was at Red House, with a couple curious otters watching us as we jumped off the boat into the water. Then we moved over to Octopus Reef, for our final dive of the certification process.

During our dives, I saw multiple species of sea stars, including a Pycnopodia helianthoides that was almost a meter wide. In addition, I found some nudibranchs, a giant decorator crab, and a gumboot chiton. I didn’t see any fish until halfway through my last dive; I was practicing a compass heading and happened to look up, only to find I was in the middle of a school of fish. I just hung out there and watched them as they watched me.

Before my diving experiences, I was nervous that I would become too afraid to be able to dive. Surprisingly, the only time I was scared during the whole weekend was when I first slid off my kayak into the water before beginning my first dive. I had not yet put on my BC, so I was just floating in my seven mm wetsuit; I slid down my mask and looked into the water. All I could see were my flippers, and below that was a green abyss. My first thought was, “what if there is a shark below me?” and I became anxious. But then I took a deep breath to calm down, put on my BC, and dove into the depths below into this new, unfamiliar and amazing world. It was an amazing experience, and I can’t wait to go diving again now that I’m certified!


Under Pressure

April 17, 2012

CTD aboard the Pt. Sur, Moss Landing

The CTD is a much used tool in the world of oceanography. We send it up and down the ocean, from surface to bottom, gathering data and water samples. As depth increases, so does the pressure. And a fun way to demonstrate the crushing pressure of a 1000 meters of water, is to literally crush things! Sending some decorated Polystyrene coffee cups along for a ride is a bit of a tradition on oceanographic cruises.  The result? Some very tiny coffee cups to place upon your desk and remind you of your adventures at sea.
