New Website Brings to Light State’s Rich Coastal and Ocean Data Inventory

SACRAMENTO, Calif. – Today the Ocean Protection Council (OPC) and the California Department of Technology launched the California Coastal Geoportal. The goal of the Coastal Geoportal is to help users learn about coastal and marine environments by facilitating the discovery and distribution of geospatial data layers. The data is accessible through the California Geoportal, the state’s go-to resource for geospatial information.

“California’s wealth of ocean and coastal information is now easily available,” said California’s Secretary for Natural Resources and Ocean Protection Council Chair John Laird. “This will lead to smarter decision-making at all levels of government as we plan for the future of our coastal communities.”

The new Coastal Geoportal provides state agency staff and the public with a user-friendly website for finding high priority coastal and marine datasets, such as aerial photos, marine protected areas, and coastal habitats, with links to the data sources. Users can view the data on a map using the Coastal Viewer, share maps, and overlay multiple data layers to see what is happening on our shoreline and out in our ocean. The Coastal Geoportal also includes a list of tools and resources where one can discover other related data holdings and tools, including the NOAA Sea Level Rise Viewer and California’s ocean observing data. This increased access to datasets will improve the use of scientific information in coastal and ocean resource management decision making.

“Today’s technology brings us many new ways to share information about the ocean and coastal environments; it allows us to collaborate with the public to achieve the goal of protecting our marine ecosystem for the future of California,” said California Lieutenant Governor and Ocean Protection Council Member Gavin Newsom. “The launch of the Coastal Geoportal is a solid step towards embracing this new technology and meeting that goal.”

The Coastal Geoportal was developed by the OPC and the Department of Technology with significant input from the California Coastal and Marine Geospatial Working Group, other state agency staff, and nongovernmental partners. This was done in response to AB 2125 (Ruskin, 2010), which directed the OPC to increase access to scientific information.

A Fish By Any Other Name

As far as I know, no fish has ever swam up to a person and said, “I am a bluefin trevally.” Yet, it is in the very nature of human beings to classify and categorize, and thus we create names for things.

A report published earlier this year by Oceana brought much needed attention to the issue of mislabeled fish in our nation’s restaurants and markets. Public health concerns, economic deception, and a possibility of fishery mismanagement were all discussed as ramifications of the level of mislabeling reported in this study. At the heart of the problem lies one central question — what to call our fish.

It turns out, the names we use for fish are quite complicated, and depending on who we are and where we are, the names we use can be quite different. Fish on a menu are usually described by their English common names. Tuna, swordfish, and sea bass are menu items we are all used to seeing. The problem is, what is tuna? Are there more than one kind of swordfish? Is sea bass a family?

As you’ll see in our latest video below, for fish on the coral reef, common names most often are in two parts, a modifier and a reference to the fish’s family. The modifier sometimes denotes physical appearance: e.g. the teardrop butterflyfish is a type of butterflyfish that has a distinct marking on its side that resembles a teardrop shape. In other instances the modifier is taken from a behavior commonly observed: e.g. the rockmover wrasse is a wrasse species that is often seen picking up and tossing rocks about in its search for prey. The problem with common names is that there is no standardization in their use. One book or snorkeler fish ID card may denote a fish as a rockmover wrasse, while another book from a different author or in a different part of the world may call that same species a dragon wrasse (still an apt name as the juvenile of this species has a markedly different appearance from the adult form and resembles a dragon as it floats about hiding like a piece of algae).

Scientists long ago recognized the problem inherent in the common name system and established an internationally-standardized naming system to alleviate this confusion.

Scientific names take their origin from the work of Swedish botanist, Carl Linnaeus. In 1753, Linnaeus published Species Planturum — the book that set the framework for what has become the modern classification system used by scientists for all living things. In this landmark work, Linnaeus described every plant that was known to him and gave each plant a two-part name consisting of a genus and a species. This system, known as binomial nomenclature, was useful to scientists as it helped organize things into groups of related organisms. Even though Linnaeus’s work long preceded the work of Charles Darwin and the theory of evolution, he was aware of seeming similarities between different plants, and he thought it made sense to group species together based on these shared characteristics.

California Wetfish Producers Association

California’s fishing industry was built largely on ‘wetfish’, so called because historically these fish were canned ‘wet from the sea’, with minimal preprocessing. Sardines, mackerel, anchovy and market squid (now called coastal pelagic species) have contributed the lion’s share of California’s commercial seafood harvest since the turn of the 20th century.

The enterprise of immigrant fishermen founded California’s wetfish industry, building up the ports of Monterey and San Pedro, San Diego and San Francisco. Today’s wetfish industry is a traditional industry with a contemporary outlook: streamlined and efficient, but still peopled by fourth and fifth-generation fishing families. Today the sons and daughters continue the enterprise begun by their fathers and grandfathers 100 years ago.

Transformed from its storied beginning, California’s wetfish industry remains an essential part of the state’s fishing culture, as well as a key contributor to our fishing economy, producing more than 80 percent of the volume and 40 percent of dockside value of all commercial fishery landings statewide.

Coastal pelagic species are also among the Golden State’s most important seafood exports. In a state that imports more than 86 percent of its seafood, the wetfish complex contributes close to 80 percent of all seafood exports, helping to offset the seafood trade imbalance.

This industry has invested in cooperative research since the beginning of the California Cooperative Fishery Investigations (CalCOFI) in the 1940s, when wetfish fishermen assessed their harvest to help fund the research partnership developed among the California Department of Fish and Game, Scripps Institution of Oceanography and the Southwest Fisheries Science Center (SWFSC).

Wetfish industry leadership established the nonprofit California Wetfish Producers Association (CWPA) in 2004, including fishermen and processors who produce most of the harvest statewide. CWPA’s mission promotes education, communication, and cooperative research to ensure sustainable fisheries.

Today CWPA’s research program continues the CalCOFI tradition, collaborating with the California Department of Fish and Wildlife and Southwest Fishery Science Center to expand knowledge of coastal pelagic species.

New Posters Highlight Local CA Seafood

Many of us may be pretty clueless about what fishermen catch off our coast, the gear they use, or the species that are farmed.

To help educate the public, California Sea Grant has created four regional posters that highlight local, commercially caught and farmed marine seafood.

The posters are available free for download and printing at Discover California Fisheries.

Gritty wharf at Port of L.A. will become marine research center

On a recent weekday morning, Daniel Pondella strode along a century-old stretch of concrete pylons and shabby warehouses in San Pedro.

As kelp swayed in the waves and terns circled overheard, Pondella recalled an elementary school field trip he took 40 years ago to this gritty wharf known as City Dock 1: “That was the day I decided to become a marine biologist.”

Now, Pondella is involved in transforming the wharf into a marine research center at the heart of the Port of Los Angeles, the nation’s busiest.

When City Dock 1 opened in 1913, it turned on a spigot for the Southern California economy through which $283 billion a year in international commerce now flows. Plans call for it to be converted into a nexus of laboratories and classrooms, fish hatcheries and berths for research vessels, which will explore the flows of Pacific currents, solutions to oceanic pollution and coastal erosion, and the rhythms of sea creatures from bacteria to 150-ton blue whales.

Fishery Management: An Analysis of Fish Stock Assessments

Center for American Progress

Counting Fish 101

An Analysis of Fish Stock Assessments

George Lapointe, Linda Mercer, and Michael Conathan   

Science is integral to fishing operations. Without the ability to estimate how many fish exist in the ocean there’s no way to determine how many of them we can catch while allowing the remaining fish populations to stay viable. But fish live in a mostly invisible world beneath the ocean surface, they move around constantly, and they eat each other.

This creates a dynamic population structure that’s incredibly difficult to track, making fish virtually impossible to count. Thus, fisheries scientists—like political pollsters or other statisticians—must rely on imperfect data to make their predictions about the status and health of fish populations.

They take these data—some of which they collect, some of which come from fishermen—and plug them into scientific models which, in turn, create estimates of population health. Because the entire population of a given species is frequently divided into subpopulations known as “stocks,” these estimates are called “stock assessments,” and they form the backbone of modern fishery management in the United States.

These assessments provide an estimate of the current state of a fish population and, in some cases, forecast future trends. This tells us whether fishery management goals are
being met and indicates the type of conditions to which the fishery will have to adapt in the near future. In an ideal world, scientists would have the resources to provide managers with updated stock assessments for each species every year, but their expense and complexity mean they can only be updated periodically.

Regardless of how frequently they can be updated, strong, science-based stock assessments are the key to future sustainability, not just of the fish but also of the fishing industry. Fishing is an inherently unstable business, yet strong, accurate science can give fishermen a better understanding of whether their resource will remain healthy, and if it does, how many fish they will be allowed to catch. This in turn allows fishermen to make informed business decisions and stabilizes coastal economies.

Sea Level’s Rise Focus of Summit

Projections of dramatic change draw group to UCSD to strategize about vulnerabilities of affected areas

LA JOLLA — Climate researchers, social scientists and policy experts from across the Pacific Rim convened at UC San Diego last week to get ahead of seas projected to rise so dramatically that they could create some of the most visible effects of global warming.

Representatives from about 20 leading research universities and nonprofit groups in South Korea, Russia, Indonesia and elsewhere met to prepare for potentially catastrophic effects on 200 million people and trillions of dollars of coastal assets.

Sea levels off most of California are expected to rise about 3 feet by 2100, according to recent projections by the National Research Council. Higher seas create challenges for port cities from San Diego to Singapore, including the potential for dramatically increased damage to coastal roads, homes and beaches — especially during storms.

“All future development has to be assessed in regards to future rises in sea level,” Steffen Lehmann, professor of sustainable design at the University of South Australia, said during the conference. “Reducing the vulnerabilities of urban (areas) is the big topic, the big task ahead of us now.”

Potential responses include managing a retreat from eroding bluffs and reshaping coastal areas to buffer development from higher water levels. “The missing link (is) between the science and those guys in planning offices and architecture firms and city municipal offices,” Lehmann said.

David Woodruff, director of the University of California San Diego’s Sustainability Solutions Institute, organized the workshop to address that problem with cross-disciplinary discussions that move toward international action.

“We are trying to affect societal change,” he said. “The sooner we start scoping options, the less expensive it will be to save current infrastructure.”

The workshop was sponsored by the Association of Pacific Rim Universities, a consortium of 42 leading research institutions. Participants drafted a report about rising sea levels for top university leaders so they can make the topic a priority with national-level leaders around the Pacific Rim.

“I really think universities can play a key role,” said UC San Diego’s Charles Kennel. “They are right at the pivot point between connecting knowledge to action. … One of the places they need to transfer their knowledge to is adaptation to climate change.”

A warming climate causes sea levels to rise primarily by heating the oceans — which causes the water to expand — and by melting land ice, which drains water to the ocean. Sea levels at any given spot depend on a complex interaction of factors, such as ocean and atmospheric circulation patterns and tectonic plate movements.

Global sea level has risen about 7 inches during the 20th century, the National Research Council said.

While sea-level-rise projections aren’t a sure thing, they are widely accepted by mainstream scientists. Skeptics see it as a waste of money to plan for problems that may not materialize for decades, or may be more modest than predicted.

International Efforts to Assess the Status of Pacific Sardine Stocks

Fisheries Resources Division

Scientists from the U.S. and Canada are working together to strengthen Pacific sardine stock assessments.  SWFSC scientists conduct regular Pacific sardine stock assessments to determine harvest guidelines for this economically important species.  In May, Canadian and NMFS scientists, together with independent experts, considered how to integrate data from Fisheries and Oceans Canada’s West Coast Vancouver Island swept-area trawl survey (WCVI) into the Pacific sardine stock assessment.

Preliminary results of the review suggest that including the Canadian survey data could strengthen and enhance the U.S. stock assessment in the future, especially as the survey evolves. Inclusion of the Canadian survey into the assessment may provide valuable insights into the northern most extension of the Pacific sardine population, the largest size classes, and the timing and extent of migration during different years. The Pacific Fishery Management Council will consider whether to incorporate the Canadian data into the U.S. stock assessment based on the independent review results. The earliest the data could be incorporated would be for the 2014 fishing season.
