  • An Offshore Bank
    Our Ocean Backyard –– Santa Cruz Sentinel columns by Gary Griggs, Distinguished Professor of Earth and Planetary Sciences, UC Santa Cruz. #271 September 16, 2018 An Offshore Bank Mountainous waves, crazy adventurers and sunken ships can all capture our interest and imagination, and there is a place off the coast of Southern California with a long history that includes all three of these. One-hundred and eleven miles due west of San Diego is an undersea mountain that rises a mile from the seafloor to within three feet of the ocean surface at low tides. Passing ships and small boats have even seen a few feet of rock exposed at the top of the mountain in the troughs of large waves from time to time. Cortes Bank appears to have been first sighted in 1846 by the frigate USS Constitution while transiting along the west coast from Monterey heading for engagement in the Mexican American War. Communication was somewhat limited in those days, however, and it was the captain of the steamship Cortes seven years later that believed he was the first to observe the waves breaking far out to sea over a shallow submarine feature in 1853. The shallow bank was named after his ship and the name stuck. It was that same year when the first U.S. Coast Survey map showed the presence of a navigational hazard in the area. The Stillwell S. Bishop, a clipper ship apparently hit the top of the seamount in 1855, but was able to continue on to San Francisco, leaving its name on the rock at the top of the bank, which it still carries today – Bishop Rock.

    PHYLOGENY AND HISTORICAL BIOGEOGRAPHY OF LIMPETS OF THE ORDER PATELLOGASTROPODA BASED ON MITOCHONDRIAL DNA SEQUENCES TOMOYUKI NAKANO AND TOMOWO OZAWA Department of Earth and Planetary Sciences, Nagoya University, Nagoya 464-8602,Japan (Received 29 March 2003; accepted 6June 2003) ABSTRACT Using new and previously published sequences of two mitochondrial genes (fragments of 12S and 16S ribosomal RNA; total 700 sites), we constructed a molecular phylogeny for 86 extant species, covering a major part of the order Patellogastropoda. There were 35 lottiid, one acmaeid, five nacellid and two patellid species from the western and northern Pacific; and 34 patellid, six nacellid and three lottiid species from the Atlantic, southern Africa, Antarctica and Australia. Emarginula foveolata fujitai (Fissurellidae) was used as the outgroup. In the resulting phylogenetic trees, the species fall into two major clades with high bootstrap support, designated here as (A) a clade of southern Tethyan origin consisting of superfamily Patelloidea and (B) a clade of tropical Tethyan origin consisting of the Acmaeoidea. Clades A and B were further divided into three and six subclades, respectively, which correspond with geographical distributions of species in the following genus or genera: (AÍ) north­ eastern Atlantic (Patella ); (A2) southern Africa and Australasia ( Scutellastra , Cymbula-and Helcion)', (A3) Antarctic, western Pacific, Australasia ( Nacella and Cellana); (BÍ) western to northwestern Pacific (.Patelloida); (B2) northern Pacific and northeastern Atlantic ( Lottia); (B3) northern Pacific (Lottia and Yayoiacmea); (B4) northwestern Pacific ( Nipponacmea); (B5) northern Pacific (Acmaea-’ânà Niveotectura) and (B6) northeastern Atlantic ( Tectura). Approximate divergence times were estimated using geo­ logical events and the fossil record to determine a reference date.

Si bien la tendencia general de las capturas de abulón indica una disminución de las dos principales especies que la conforman (Haliotis fulgens y H corrugata), a partir de su máximo histórico en 1950, esta tendencia no ha sido uniforme ni entre especies ni entre las regiones de donde se extrae.

  • Guide to the Coastal Marine Fishes of California
    STATE OF CALIFORNIA THE RESOURCES AGENCY DEPARTMENT OF FISH AND GAME FISH BULLETIN 157 GUIDE TO THE COASTAL MARINE FISHES OF CALIFORNIA by DANIEL J. MILLER and ROBERT N. LEA Marine Resources Region 1972 ABSTRACT This is a comprehensive identification guide encompassing all shallow marine fishes within California waters. Geographic range limits, maximum size, depth range, a brief color description, and some meristic counts including, if available: fin ray counts, lateral line pores, lateral line scales, gill rakers, and vertebrae are given. Body proportions and shapes are used in the keys and a state- ment concerning the rarity or commonness in California is given for each species. In all, 554 species are described. Three of these have not been re- corded or confirmed as occurring in California waters but are included since they are apt to appear. The remainder have been recorded as occurring in an area between the Mexican and Oregon borders and offshore to at least 50 miles. Five of California species as yet have not been named or described, and ichthyologists studying these new forms have given information on identification to enable inclusion here. A dichotomous key to 144 families includes an outline figure of a repre- sentative for all but two families. Keys are presented for all larger families, and diagnostic features are pointed out on most of the figures. Illustrations are presented for all but eight species. Of the 554 species, 439 are found primarily in depths less than 400 ft., 48 are meso- or bathypelagic species, and 67 are deepwater bottom dwelling forms rarely taken in less than 400 ft.

  • Localized Depletion of Three Alaska Rockfish Species Dana Hanselman NOAA Fisheries, Alaska Fisheries Science Center, Auke Bay Laboratory, Juneau, Alaska
    Biology, Assessment, and Management of North Pacific Rockfishes 493 Alaska Sea Grant College Program • AK-SG-07-01, 2007 Localized Depletion of Three Alaska Rockfish Species Dana Hanselman NOAA Fisheries, Alaska Fisheries Science Center, Auke Bay Laboratory, Juneau, Alaska Paul Spencer NOAA Fisheries, Alaska Fisheries Science Center, Resource Ecology and Fisheries Management (REFM) Division, Seattle, Washington Kalei Shotwell NOAA Fisheries, Alaska Fisheries Science Center, Auke Bay Laboratory, Juneau, Alaska Rebecca Reuter NOAA Fisheries, Alaska Fisheries Science Center, REFM Division, Seattle, Washington Abstract The distributions of some rockfish species in Alaska are clustered. Their distribution and relatively sedentary movement patterns could make localized depletion of rockfish an ecological or conservation concern. Alaska rockfish have varying and little-known genetic stock structures. Rockfish fishing seasons are short and intense and usually confined to small areas. If allowable catches are set for large management areas, the genetic, age, and size structures of the population could change if the majority of catch is harvested from small concentrated areas. In this study, we analyzed data collected by the North Pacific Observer Program from 1991 to 2004 to assess localized depletion of Pacific ocean perch (Sebastes alutus), northern rockfish S.( polyspinis), and dusky rockfish (S. variabilis). The data were divided into blocks with areas of approxi- mately 10,000 km2 and 5,000 km2 of consistent, intense fishing. We used two different block sizes to consider the size for which localized deple- tion could be detected. For each year, the Leslie depletion estimator was used to determine whether catch-per-unit-effort (CPUE) values in each 494 Hanselman et al.—Three Alaska Rockfish Species block declined as a function of cumulative catch.

This year PBC will hold its 11th Annual Pacifica Earth Day of Action and EcoFest, "Bee the Change, Bee an Earth Hero," on the 18th of April. How do they do it? How do they get the word out to bring so many people together? How do they supply volunteers with cleanup and planting tools and the information needed to tackle the various projects? How do they bring so many world-renowned speakers not only to the stages of the event's EcoFest but into local classrooms in the weeks leading up to event? A huge part of getting it all off the ground is the Beach Coalition's annual and extremely popular Surf Movie event, a benefit that allows the local nonprofit to benefit our city.
