The identify Christopher Lowe, a professor of marine biology at Lengthy Seashore State, has turn into synonymous with the on-campus Shark Lab. For years, Lowe has served as a guiding captain, overseeing the lab’s numerous analysis tasks. But, the Shark Lab is removed from a one man operation. Somewhat, Lowe’s imaginative and prescient of using the lab as a medium to review the physiological and behavioral ecology of marine animals is made potential by a collective of individuals — nearly all of that are scholar volunteers.

With a purpose to analysis the inhabitants of white sharks dwelling alongside the Golden State’s coast, the lab lately acquired a $three.75 million contract from the state of California. Two most important aims of the analysis challenge, coined the “White Shark Project,” embrace gaining a higher understanding of the rising shark inhabitants in addition to enhancing seashore security. Most of the lab’s volunteers, in addition to its paid researchers and technicians, are concerned.

“So, we know that white sharks use our beaches as nurseries — a lot of young white sharks hang out along the beaches and they are in and among swimmers and surfers,” Lowe stated. “There’s a concern about the risk of that interaction, but there’s no scientific data to demonstrate that it’s dangerous.”

Lowe calls his group of researchers “shark spies.” Apart from specializing in learning the conduct of sharks, the lab additionally researches what sort of dangers sharks pose to people. The Shark Lab has been researching this since its early days after opening in 1966. The know-how used then was a lot much less superior; nevertheless, the researchers’ strategies of buying info have been nonetheless spectacular.

For instance, Donald Nelson, the previous director of the Shark Lab, developed a man-operated moist sub, coined the SOS II — brief for Shark Statement Submersible, which he used to review aggressive conduct emitted by sharks. For research, Nelson would movie himself purposefully chasing sharks whereas working the SOS II till the sharks started eliciting a threatening response, based on Lowe.

“So what he figured out is sharks exhibit a body language where they drop their pectoral fins, they arch their back, they go into this exaggerated swimming behavior, which, at the time, we as humans, never really saw before. We just thought it was odd, but we couldn’t interpret it,” Lowe stated.

Findings like these, coupled with Nelson’s groundbreaking use of acoustic telemetry to review sharks, helped advance the shark lab into one of many nation’s main retailers for the research of sharks and their conduct. The know-how used at the moment — akin to innocent monitoring system transmitters which connect to sharks as a way to purchase knowledge and underwater receivers able to figuring out a shark’s location — is as state-of-the-art because it has ever been.

At present, the lab employs eight graduate college students, a postdoctoral researcher, three technicians and roughly 80 undergraduate college students — lots of which both volunteer or work within the lab. Moreover, the lab receives assist from about 40 to 60 volunteers from the neighboring Lengthy Seashore group, in response to Lowe.  

 

Scholar Highlight

Biology graduate studenr Taylor Smith collects armored sea stars to be noticed in an undergraduate invertebrate zoology class (11/27).

Taylor Smith

First yr graduate scholar of biology, Taylor Smith loves sharks. Smith graduated with a bachelor’s diploma in marine biology from College of California, San Diego. Shortly after commencement, she started looking for work at a lab that primarily focuses on shark analysis. Fortunate for her, the LBSU Shark Lab does precisely that.

“A lot of labs [at other universities] will focus on a lot of different animals but not really have a specific focus for a wide range of topics with one animal,” Smith stated. “The sharks that we focus on [at the LBSU Shark Lab] we look at from metabolism or contaminants or more ecological purposes and studies. So there was a lot more you can do with sharks versus one small section.”

Her ardour for all-things sharks has helped her grow to be one of many Shark Lab’s most versatile members as a result of she is prepared to work on any task involving sharks.

Smith works with the lab’s instructional outreach program in addition to the “Jaws ID’ing program.” This program has no correlation with the 1975 Steven Spielberg movie and every little thing to do with the categorization of precise shark jaws. Given an abundance of various shark jaws by The California Division of Fish and Wildlife, Smith and the opposite lab members at the moment are within the strategy of figuring out and classifying which jaws belong to their respective species.

Apart from that, Smith is presently engaged on the “Juvenile White Shark Project.” She scuba-dives into the ocean to assist with the lab’s acoustic telemetry work. This work is essential to be able to detect what areas sharks are migrating towards.

Nevertheless, her upcoming task may be her most formidable one but. Inside the subsequent six months, Smith will journey to Alaska, on behalf of the LBSU Shark Lab, to analysis the longevity of the Pacific Sleeper Shark, a species which has an estimated lifespan of lots of of years.

“The Greenland shark which is closely related to the species I’ll be working with, the Pacific Sleeper, was recently found last year, or two years ago, to live between 272 and 512 years,” Smith stated. “So we assume that Pacific Sleepers have a similar longevity. So we want to see what mechanism could lead them to live for so long.”

Smith shared that probably the most rewarding elements about working on the Shark Lab has been working alongside Lowe.

“He definitely pushes you beyond what you think you can do,” Smith stated.

Arthur Barraza

Though the Shark Lab focuses on researching totally different shark species — Arthur Barraza, an LBSU alumnus who graduated with a diploma in science and biology final spring, is greatest recognized within the lab for his analysis on inexperienced sea turtles. Formally, he’s the lab’s fiscal operations coordinator and in addition helps with administrative issues. Lowe calls Barraza his “fixer.” Based on Barraza, it isn’t unusual for Lowe to easily ask him to repair no matter drawback arises on the lab.

“The green sea turtles [research project] was my master’s project,” Barraza stated. “Oddly enough, I was part of the shark lab but studying green sea turtle toxicology.”

Barraza’s graduate thesis concerned evaluating hint metals and pollution in inexperienced sea turtles present in Seal Seashore and San Diego Bay. He would get hold of each blood and shell samples from the turtles, so as to look at how their tissues have been affected by the polluted ocean water on the two places.

Though Barraza continues to work with inexperienced sea turtles alongside the California coast, he’s labored because the lab’s fiscal operations coordinator for the previous three months. Barraza stated he feels that he’s grown considerably as a scientist inside that time-frame.

What drew Barraza to the Shark Lab, and has finally inspired him to remain, are the fascinating, albeit difficult, analysis tasks at present in movement.

“I knew this was going to be a lab that was very intense,” Barraza stated. “But that’s when you learn the most. I was really attracted to that, in general.”

Alyssa Clevenstine is a third yr science and biology graduate scholar who started working on the LBSU Shark Lab in Might 2016 (11/27).

Alyssa Clevenstine

The shark lab is residence to a number of totally different marine species apart from sharks. The lab homes a number of stingrays and recreation fish. Just like Barraza, third yr graduate scholar of science and biology, Alyssa Clevenstine’s focus of analysis is not essentially on sharks, however fairly on big sea bass.

“Giant sea bass are a pretty popular topic of science right now because they were exploited throughout most of the 20th century — just recently are we starting to see their numbers increasing,” Clevenstine stated.

Her analysis on big sea bass is just like the sort of work underway within the “White Shark Project,” because the applied sciences and telemetry utilized in each are comparable.

“We do external tagging, the same way that we do for white sharks. What’s different though is that we do it underwater,” Clevenstine stated. “So, I do a lot of scuba diving as a scientific scuba diver — so do a lot of members of my lab.”

She and her colleagues tag big sea bass which are three to 6 ft lengthy. Nevertheless, slightly than concentrate on giant scale annual actions made by the ocean bass, Clevenstine is specializing in aggregation among the many marine species and figuring out the expansion inside a inhabitants of sea bass. Most of her work is accomplished close to Santa Catalina Island.

Clevenstine has been working on the Shark Lab since Might 2016. On the lab, it is widespread for her to work anyplace between 5 to 7 days a week for round 10 hours a day. Though the workload could also be demanding for a scholar, she considers her work on the lab to be profusely useful when it comes to her improvement as a scientist.

“Dr. Lowe has been exceedingly helpful. He doesn’t lead you directly on the path that you need to go on,” Clevenstine stated. “He allows you to bob and weave and do what you need to do. If you’re screwing up, or if you’re doing something too bad, then he’ll help you get back on the right path. But it’s been a really helpful experience because he’s a little more hands-off in terms of building your own career.”

The Shark Lab’s semi-enclosed outdoors lab, situated at HSCI – 121a, is recognized for internet hosting open homes for campus group members excited about getting a nearer take a look at the housed marine species. Comply with @CSULBsharklab on Twitter for information relating to upcoming occasions on the lab.
