attribute NC_GLOBAL acquisition_description String Acoustic data were collected nearly continuously using Simrad EK60s at 4\nfrequencies (38, 70, 120, and 200 kHz). Split beam transducers (Simrad model\nnumbers: 38-12, 70-7c, 120-7c, 200-7c) were mounted 1.5 m below the surface on\na rigid pole. Each transmitted a 512 us pulse as frequently as possible for\nthe water depth. Raw data were stored using Simrad ER60 software.\n \nNoise from splash down, electrical interference, and CTD casts were flagged as\n\\u2018bad data\\u2019 using Echoview software before integration. Acoustic\nbackscattering values at 38 kHz that were greater than -75 dB were integrated\nin 1 km horizontal bins from depths of 5m to 500m or 1 m above the bottom,\nwhichever was shallower. These integrated, area scattering values or Nautical\nArea Scattering Coefficients (NASC: m2 nmi-2) are provided.

attribute NC_GLOBAL project String Jumbo Squid Physiology
attribute NC_GLOBAL projects_0_acronym String Jumbo Squid Physiology
attribute NC_GLOBAL projects_0_description String This project concerns the ecological physiology of Dosidicus gigas, a large squid endemic to the eastern Pacific where it inhabits both open ocean and continental shelf environments. Questions to be addressed include:\n1) How does utilization of the OML by D. gigas vary on both a daily and seasonal basis, and how do the vertical distributions of the OML and its associated fauna vary?\n2) What behaviors of squid are impaired by conditions found in the OML, and how are impairments compensated to minimize costs of utilizing this environment? and\n3) What are the physiological and biochemical processes by which squid maintain swimming activity at such remarkable levels under low oxygen conditions?\nThe investigators will use an integrated approach involving oceanographic, acoustic, electronic tagging, physiological and biochemical methods. D. gigas provides a trophic connection between small, midwater organisms and top vertebrate predators, and daily vertical migrations between near-surface waters and a deep, low-oxygen environment (OML) characterize normal behavior of adult squid. Electronic tagging has shown that this squid can remain active for extended periods in the cold, hypoxic conditions of the upper OML. Laboratory studies have demonstrated suppression of aerobic metabolism during a cold, hypoxic challenge, but anaerobic metabolism does not appear to account for the level of activity maintained. Utilization of the OML in the wild may permit daytime foraging on midwater organisms. Foraging also occurs near the surface at night, and Dosidicus may thus be able to feed continuously. D. gigas is present in different regions of the Guaymas Basin on a predicable year-round basis, allowing changes in squid distribution to be related to changing oceanographic features on a variety time scales.\nThis research is of broad interest because Dosidicus gigas has substantially extended its range over the last decade, and foraging on commercially important finfish in invaded areas off California and Chile has been reported. In addition, the OML has expanded during the last several decades, mostly vertically by shoaling, including in the Gulf of Alaska, the Southern California Bight and several productive regions of tropical oceans, and a variety of ecological impacts will almost certainly accompany changes in the OML. Moreover, D. gigas currently supports the world's largest squid fishery, and this study will provide acoustic methods for reliable biomass estimates, with implications for fisheries management in Mexico and elsewhere.\nThis award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). This is a Collaborative Research project encompassing three NSF-OCE awards.\nBackground Publications:\nStewart, J.S., Field, J.C., Markaida, U., and Gilly, W.F. 2013.
