ECE’s Manjunath part of collaborative marine Biodiversity Observation Network (BON) centering on Santa Barbara Channel

October 30th, 2014

“One Giant Step for Ocean Biodiversity” — the marine Biodiversity Observation Network in the Santa Barbara Channel has been established to addresses an information gap about marine habitats.

With 13 scientific investigators and 10 partner institutions, the marine biodiversity observation network (BON) centered on the Santa Barbara Channel is the epitome of collaboration. Funded with $5 million by NASA, the Bureau of Ocean Energy Management (BOEM) and the National Oceanic and Atmospheric Administration (NOAA), the UC Santa Barbara-led project officially kicked off Thursday, Oct. 23, at UCSB’s Marine Science Institute (MSI).

“We’ve got principal investigators here from two colleges, a professional school, over six different department on campus, as well our friends at NOAA,” said MSI Director Mark Brzezinski. “It’s an incredibly interdisciplinary team ranging from biology to engineering, and it’s no small feat to bring that kind of group together. Here at UCSB, we really pride ourselves on this kind of interdisciplinary work. It’s our normal mode of operation.”

Designed to fill a gap not addressed by NASA’s Group on Earth Observations (GEO) BON, which focuses on terrestrial biomes, this prototype marine BON seeks to eventually cover a huge range of biodiversity in the oceans. The effort begins in the Santa Barbara Channel where various groups have been gathering a breadth of scientific data ranging from intertidal monitoring to physical oceanographic measurements.

“There have been a huge number of observations taken over time in the channel,” said Robert Miller, a research biologist with MSI and a principal investigator of the marine BON. “The channel has also been a hotspot for remote sensing research, which gives us a wider picture of the area, which we can then match with in-situ observations.”

The marine BON has three goals: to integrate biodiversity data to enable inferences about regional biodiversity; to develop advanced methods in optical and acoustic imaging and to improve monitoring biodiversity in partnership with ongoing monitoring and research programs; and implement a tradeoff framework that optimizes allocation of sampling effort, given the cost of that effort and the information gained from it.

UCSB investigators involved in the project are B.S. Manjunath, director of UCSB’s Center for Bio-Image Informatics; Craig Carlson, chair of the Department of Ecology, Evolution and Marine Biology (EEMB); Deborah Iglesias-Rodriguez, an EEMB professor; Phaedon Kyriakidis, a professor in the Department of Geography; Kevin Lafferty, a principal investigator with MSI and a marine ecologist with the United States Geological Survey’s Western Ecological Research Center; Milton Love and Daniel Reed, research biologists with MSI; Douglas McCauley, an assistant professor in EEMB; Andrew Rassweiler, an assistant research biologist at MSI; and David Siegel, director of the Earth Research Institute. Additional investigators include Andrew Thompson of NOAA’s Southwest Fisheries Science Center.

UCSB scientists lead a team designing a network to track many species of marine organisms over time

Is life in the oceans changing over the years? Are humans causing long-term declines in ocean biodiversity with climate change, fishing and other impacts? At present, scientists are unable to answer these questions because little data exist for many marine organisms, and the small amount of existing data focuses on small, scattered areas of the ocean.

“Currently most of the information we have for marine species is on economically important species like fish and lobster,” said Robert Miller, a research biologist at UC Santa Barbara’s Marine Science Institute. “Little is known about the majority of species out there, even though they may be very important from an ecological point of view. A comprehensive observation network that looks at a broad suite of marine organisms would tell us how marine ecosystems as a whole are doing.”

A group of researchers from UCSB, the USGS, NOAA, National Marine Fisheries Service and UCSD’s Scripps Institution of Oceanography are creating a new prototype system — the Marine Biodiversity Observation Network — to solve this problem. The five-year project led by Miller will center on the Santa Barbara Channel, but the long-term goal is to expand the network around the country and around the world to track over time the biodiversity of marine organisms, from microbes to whales. After a highly competitive proposal process, NASA, the Bureau of Ocean Energy Management (BOEM) and NOAA chose to fund UCSB’s approximately $5 million project.

The Marine Biodiversity Observation Network will integrate existing data over large spatial scales using geostatistical models and will utilize new technology to improve knowledge of marine organisms. Scientists will rely on genetics to accomplish three goals: begin learning about the many kinds of microbes in our coastal waters; identify plankton that would otherwise have to be counted under the microscope over many, many hours; and detect larger animals such as whales and fish by looking for fragments of DNA they have shed into the water. This is known as environmental DNA or eDNA.

The group will use imaging to survey organisms such as kelp forests and deep reefs in underwater habitats where dive-time constraints limit the ability for firsthand exploration. To further this effort, UCSB’s Center for Bio-Image Informatics will use advanced image analysis to automatically identify different species including fish.

Electrical and Computer Engineering is one of the most popular disciplines with 90 graduate students among the 758 new graduate students entering UCSB. These incoming students are diverse in many ways, such as their ages, countries of origin, and fields of study.

Ehsan Omidi comes to UCSB all the way from Tehran, Iran. He earned both a bachelor of science and a master of science in electrical engineering from Amirkabir University of Technology in Tehran. He enters the Ph.D. program in electrical and computer engineering under guidance of Associate Professor Yasamin Mostofi with a concentration in control, communication, and signal processing.

Both of Omidi’s parents were schoolteachers, and he has always excelled in academics. Growing up, he had many of the same hobbies as his friends, including soccer, cartoons and video games.

“But,” he said, “my real hobby started when we had a computer in our home and I started programming with it. Since then, programming has been my main entertainment.”

When he realized that computer programming didn’t challenge him enough, he began to study electrical engineering in order to figure out what goes on inside a computer. He also worked on his university’s robotics team in creating a simple robot that could do funny tasks such as playing with a golf ball.

Omidi is very excited to be studying at UCSB, which is among the top 10 engineering schools in the world (Academic Ranking of World Universities). It also doesn’t hurt that Santa Barbara is, in Omidi’s words, “totally a perfect city.” He said, “Living in an always-sunny city with beautiful landscapes wherever you look and doing your desired research is what every grad student dreams.”

Omidi’s hobbies include soccer, violin and chess, and he hopes to add hiking and surfing in Santa Barbara to the list.

UC Santa Barbara Professors Kaustav Banerjee (ECE) & Samir Mitragotri (ChemE) and graduate student researcher Deblina Sarkar demonstrate atomically thin, ultrasensitive and scalable molybdenum disulfide field-effect transistor based biosensors and establish their potential for single-molecule detection

Move over, graphene. An atomically thin, two-dimensional, ultrasensitive semiconductor material for biosensing developed by researchers at UC Santa Barbara promises to push the boundaries of biosensing technology in many fields, from health care to environmental protection to forensic industries.

Based on molybdenum disulfide or molybdenite (MoS2), the biosensor material — used commonly as a dry lubricant — surpasses graphene’s already high sensitivity, offers better scalability and lends itself to high-volume manufacturing. Results of the researchers’ study have been published in ACS Nano.

“This invention has established the foundation for a new generation of ultrasensitive and low-cost biosensors that can eventually allow single-molecule detection — the holy grail of diagnostics and bioengineering research,” said Samir Mitragotri, co-author and professor of chemical engineering and director of the Center for Bioengineering at UCSB. “Detection and diagnostics are a key area of bioengineering research at UCSB and this study represents an excellent example of UCSB’s multifaceted competencies in this exciting field.”

The key, according to UCSB professor of electrical and computer engineering Kaustav Banerjee, who led this research, is MoS2’s band gap, the characteristic of a material that determines its electrical conductivity.
