Things that go “bump” in the ocean

When Jacques-Yves Cousteau gave the world it’s first video footage of the ocean in color, he named this documentary The Silent World.  Perhaps as a result, most of us think of the ocean as a quiet refuge, punctuated by occasional humpback whale songs or clicks from a passing pod of dolphins.  In recent years, scientists have dipped microphones into the water and discovered that this could not be further from the truth.

The Ballast Team Goes to Sea

July 17, 2014

Those of us working on the ballast project in the Biological Oceanography lab are closely tied with the Cal Maritime Academy and their training ship, the Golden Bear. So, wherever the ship goes, we go! This summer’s training cruise for the cadets took the Golden Bear across the Pacific from San Francisco, California to Busan, South Korea, then throughout the South Pacific and eventually to the island of Saipan. One of our team members, Marilyn Cruickshank, volunteered on the trans-Pacific crossing, gathering surface water samples along the way and conducting a variety of assays to get an idea of the biomass out in the open ocean.

Once in Busan, the rest of our team joined Marilyn to test the ballast water treatments systems currently onboard the Golden Bear.  In order to determine if the treatment systems are truly effective, it is important to test in environments that are challenging enough and have a high number of organisms. We were able to conduct a few tests in the productive waters near South Korea and once again when the ship took a quick detour to Manila Bay in the Philippines.

When we weren’t testing ballast treatment systems, the team continued surface water sampling and analysis of biomass in the waters of the South Pacific. Specifically, we were interested in the new ATP measurement method that Jules Kuo developed as part of her thesis project in comparison with the traditional oceanographic ATP measurement methods that have been used for decades.

Our trip concluded in Saipan, where we were able to enjoy a little time off to snorkel in the beautiful waters surrounding the island. The ballast team flew back to California but the Golden Bear will continue sailing throughout the Pacific. Later this summer, we will re-board in southern California for another round of tests!

Looking forward to the second part of the cruise!

On June 5th, members of the Marine Pollutions Studies and Chemical Oceanography Labs under the direction of Dr. Kenneth Coale, began a week-long journey on the R/V Point Sur to investigate the recent findings of mercury in coastal marine fog. Dubbed “The Fog Cruise”, the crew and science party aboard sampled near and offshore waters using oceanographic tools for signs of methylmercury (MeHg), from deep sea sediments to fog above the sea surface.

The Success of Open House 2014

May 10, 2014

By Melissa Nehmens PSRC

This past weekend, Moss Landing Marine Labs opened our doors and welcomed everyone to our annual Open House event. For those of you new to Moss Landing traditions (as I am as a first year student), it is an event we hold every year in the Spring that is organized by the student body and hosted by the students, faculty, and staff.

We take Open House as an opportunity to share our research in a fun, yet educational way. Just to name a few exciting activities:  the Invertebrate Zoology and Molecular Ecology lab had an invertebrate touch tank where you could see, touch, and learn about all of our interesting local invertebrates.

If you have been able to attend in previous years, you know that we will even cook for you!  Here is a teaser recipe from last year’s table of baked goods:

Chocolate peanut clusters (gluten free & vegan)

By Jen Raanan

Shopping List:

1 bag chocolate chips (I use dark/semisweet)

1 cup peanut butter

1 large canister dry roasted peanuts (salted or unsalted, depending on your taste. I use salted because my peanut butter is low-sodium.)

Directions:
1) in a double-boiler, melt chocolate & peanut butter. Don’t get water in the mixture. It ruins the chocolate!

2) Remove mixture from heat and stir in peanuts until they’re completely coated.

3) Spoon mixture into bite-sized or cookie-sized drops onto a cookie sheet lined with parchment paper

4) Chill in fridge until chocolate sets

5) Clusters can be stored in fridge or freezer

Enjoy!

MLML goes to Baja – the trip continues

March 17, 2014

Jackie Lindsey By Jackie Lindsey, Vertebrate Ecology Lab

For the next two weeks Moss Landing Marine Labs will be a little quieter, and not just because of spring break.  A large class of graduate students has just departed for Baja California Sur for two weeks of field research, and I am lucky to be among them!   Many of us have never been to this part the world, and we are full of hopes and dreams that we can pull off the projects we designed back in the classroom.

El Pardito

El Pardito

We are spending the majority of our trip on a tiny island called El Pardito, located within the Sea of Cortez.  This island is home to a small community of fishermen who have lived on the island for generations.  Many of us are depending heavily on their expertise to set up our projects and navigate the local waters.

Our projects range from mapping benthic habitat, to monitoring Marine Protected Areas, to studies of sea turtles and damselfish. We are spending full days in and on the water around El Pardito, and the weather should be just about perfect (fingers crossed)!

When we get back there will be plenty of pictures to post, commemorating our journey and all our hard work, but for now let me leave you with this image of NOT EVEN ALL OF THE GEAR!  Food, cooking tools, boats, compressors, dive gear, camping gear, sampling gear…the list goes on and on (and on and on).

I hope we didn’t forget anything because it’s too late now!  See you in two weeks!

Sometimes You Have to Celebrate!

March 5, 2014

Back in December 2013 I went on my last sampling bout for my thesis to Santa Catalina Island. My team included three amazing colleagues from Moss Landing Marine Laboratories. We conducted surveys in sand and rhodolith beds which will be used to compare the communities. Rhodoliths are free-living calcareous algae that look like little pink tumbleweeds and propagate above sand.

Rhodolith

They appear to provide diverse structure increasing abundance and diversity of flora and fauna, similar to how trees provide habitat for epiphytic plants, climbing vines, and animals like birds and mammals.

We conducted surveys to estimate the abundance of macroalgae growing on each substrate, macroinvertebrates, fishes, and took cores for later sorting under a microscope to estimate microinvertebres within each substrate. We celebrated by wearing santa hats which made the long sampling dives more fun. It was a great way to finish up my thesis.

Journey to the Center of the Slough

February 14, 2014

by Catarina Pien, PSRC Lab

If you’ve ever visited our lab, you’ve seen the beautiful waters surrounding us, often bobbing with a variety of marine mammals. The main body of water that surrounds Moss Landing Marine Laboratories is Elkhorn Slough, which is an estuarine embayment that drains into the Monterey Bay.

Elkhorn Slough has evolved greatly in the past few centuries. Since the dredging of Moss Landing Harbor in 1946, the slough has become directly connected and thus heavily influenced by the Monterey Bay. This connection has led the slough to change from a freshwater-influenced estuary to a predominantly saltwater-influenced and erosional body of water. A great deal of research has been done to study how these changes have influenced habitat structure and biological communities in the slough.

My own thesis research will focus on Elkhorn Slough, and how various oceanographic variables have changed and are influencing elasmobranch (shark and ray) populations in the slough. I am hoping that the class will be beneficial in showing me how to measure chemical variables, and analyze values in terms of how they influence biological communities.

Last week, our chemical oceanography class was split into five groups and deployed to various water bodies around our school to take some measurements and water samples. It had just rained earlier that week, so we were hoping there would be some visible differences in salinity and nutrient content in the regions we were sampling. Although the main channel of Elkhorn Slough is heavily influenced by the Monterey Bay, and thus oceanographically similar to the ocean, the upper reaches of the slough are often less saline (depending on the season), and more influenced by precipitation. One group went offshore to Monterey Bay, two groups went into Elkhorn Slough, one drove around to Salinas River, Carneros Creek, and other connected sloughs, and my group sampled in Moss Landing Harbor.

We took one of our school’s whalers on a beautiful sunny morning, excited (though some of our facial expressions may not be representative) and ready to sample.

We motored slowly through the harbor, observing sea lions sunning themselves, and being observed by harbor seals and a portly sea otter.

Once at a station, we used the CTD (Conductivity Temperature Depth) to measure salinity, temperature, and pH at eight stations within our region.

We also recorded GPS coordinates, and collected water samples with a syringe, and filtered them into a bottle to bring back to the lab.

Many of the changes to Elkhorn Slough have been anthropogenic, including the construction of levees, dikes, tide gates, salt ponds, and railroads. Some of these were constructed early on for agriculture and ranching, whereas others have been created to remedy erosional problems we have created.  These barriers have altered tidal flow within Elkhorn Slough, and created distinct oceanographic areas. In order to determine differences between these areas, some stations required us to leave the boat to sample adjacent areas that were separated by a barrier.

We passed by the lab, hoped we wouldn’t embarrass ourselves in front of the whole lab, and successfully finished our collections near the tide gate leading to the Old Salinas River.

MLML!

Combined with the rest of the teams, we now have oceanographic measurements and water samples all around Elkhorn Slough and the surrounding bodies of water. Over the course of the semester, we will learn how to measure phosphate, nitrite/ nitrate, oxygen, silicate, and alkalinity of the water samples. The measurements will tell us something about how how the stations differ from each other, how Elkhorn Slough is partitioned, and the outside influences to each station.

As marine scientists, many of us spend a substantial chunk of time in the field. While field work can be frustrating and tiring, on a beautiful day like this, encountering a multitude of wildlife and puttering slowly through the beautiful waters, it is easy to remember why we went into the field of marine science.

Whalefest: Not Just a Tale of Whales

On January 25th and 26th, the Monterey Fisherman’s Wharf held its 4th annual Whalefest event to celebrate the migration of grey whales. Thanks to the efforts of fellow Pacific Shark Research Center (PSRC) student, Kristin Walovich, the PSRC and Friends of Moss Landing Marine Labs, hosted a booth at the event, speaking to attendees and passersby about what Moss Landing Marine Labs is all about!

Table attractions for the PSRC included a dehydrated Mako shark head and shark fin from our museum collection, and an anatomical model of a great white that allows you to see the inside of a shark. An interactive matching game, created by PSRC student Jessica Jang, was another favorite allowing people to test their shark knowledge by matching a shark to its description and name. We also showcased a story done by Central Coast News, interviewing PSRC director, Dave Ebert, about the lab’s role in international shark research.

May the Flow Be With You!

January 22, 2014

Scott GabaraBy Scott Gabara, Phycology “Seaweed” Lab

Circulating seawater systems are very important for marine laboratories as they need to keep organisms from the ocean alive and use the water to aid in conducting experiments.  We have recently had our Moss Landing Marine Laboratories offshore intake upgraded and we went on a dive to inspect its current status.  The large meshed cylinder sucks in water and supplies our lab with flowing seawater.  We routinely inspect and clean the surface of the grates and the structure.

It is interesting to see what invertebrates recruit or move onto the structure.  With sand surrounding us we create a small oasis of life concentrated on the hard substrate.  One of the issues we have to deal with is that seawater contains invertebrate larvae and some species will settle on the inside the pipes and eventually constrict and clog our flow, similar to plaque buildup in an artery.  We have to force a Pigging Inspection Gauge (PIG), a tool which is usually a piece of cylindrical foam, through the inside of the pipe to clean and clear the walls.  It’s great we can get routine cleanings so our seawater system continues flowing and our lab doesn’t have a “heart attack”!
