    Questioning the rise of gelatinous zooplankton in the world's oceans
    (American Institute of Biological Sciences, 2012-02) Condon, Robert H. ; Graham, William M. ; Duarte, Carlos M. ; Pitt, Kylie A. ; Lucas, Cathy H. ; Haddock, Steven H. D. ; Sutherland, Kelly R. ; Robinson, Kelly L. ; Dawson, Michael N. ; Decker, Mary Beth ; Mills, Claudia E. ; Purcell, Jennifer E. ; Malej, Alenka ; Mianzan, Hermes ; Uye, Shin-Ichi ; Gelcich, Stefan ; Madin, Laurence P.
    During the past several decades, high numbers of gelatinous Zooplankton species have been reported in many estuarine and coastal ecosystems. Coupled with media-driven public perception, a paradigm has evolved in which the global ocean ecosystems are thought to he heading toward being dominated by “nuisance” jellyfish. We question this current paradigm by presenting a broad overview of gelatinous Zooplankton in a historical context to develop the hypothesis that population changes reflect the human-mediated alteration of global ocean ecosystems. To this end, we synthesize information related to the evolutionary context of contemporary gelatinous Zooplankton blooms, the human frame of reference for changes in gelatinous Zooplankton populations, and whether sufficient data are available to have established the paradigm. We conclude that the current paradigm in which it is believed that there has been a global increase in gelatinous Zooplankton is unsubstantiated, and we develop a strategy for addressing the critical questions about long-term, human-related changes in the sea as they relate to gelatinous Zooplankton blooms.

    Comparison of recruitment dynamics in five intertidal marine invertebrates following mass mortality along the northeastern Pacific coastline in 2005 (CHIPS project)
    (Biological and Chemical Oceanography Data Management Office (BCO-DMO). Contact: bco-dmo-data@whoi.edu, 2022-08-19) Dawson, Michael N. ; Gaylord, Brian ; Grosberg, Richard K.
    Twenty accessible rocky intertidal sites were selected to span the ‘kill-zone’ and peripheral locations (see list of sites in Schiebelhut et al. in prep; see also Jurgens et al. 2015). Two rocky intertidal areas were sampled per site, usually one on either side of the point of entry onto the beach and separated by approximately 100 m. We used quadrats (1m2 [4 * 0.25 m^2] or 0.0625 m^2) and swaths (2 m wide transects) to estimate juvenile and adult abundance for each target species. This data set includes counts of Pisaster ochraceus, Cryptochiton stelleri and Leptasterias sp. in quadrats and swaths along the California coast from 37.9 N to 38.9 N. The CHlPS-02 dataset has some overlap with the CHlPS-01 dataset. Data that share the same location and date represent the same collections. In the CHlPS-01 dataset from Jurgens et al. (2015), the datum presented is the sum of individuals across life-stages and across areas-within-site for each species. In the CHlPS-02 dataset from Schiebelhut et al., the data presented are the total counts within life-stage (recruit or adult) and within-area-within-site for each species. Thus, for example, for Arena Cove on 02 December 2013, the CHlPS-01 dataset states there were 44 Henricia; the CHlPS-02 dataset states there were 6 recruits plus 4 adults in Area 1 and 15 recruits plus 19 adults in Area 2.
