The workshop and symposium titled Sustainable Small-scale Fisheries: Towards FAO Guidelines on Marine and Inland Small-scale Fisheries was jointly organized by the National Fishworkers’ Forum (NFF) and the Society for Direct Initiative for Social and Health Action (DISHA), in collaboration with the International Collective in Support of Fishworkers (ICSF). The workshop was the first in a series of consultations around the world organized to discuss the Voluntary Guidelines on Small-scale Fisheries (VGSSF) and propose measures, keeping in mind the interests and concerns of small-scale fisheries and fishing communities. The workshop was also a forum to make the role of small-scale fisheries and fishworkers more visible in the context of food security, poverty alleviation and sustainable use of fishery resources. The workshop had 62 participants from both the marine and inland sectors, representing 10 States of India. The participants included fishworkers, representatives of fishworker organizations, policymakers and representatives of multilateral organizations. The workshop was structured to facilitate active interaction and discussion among participants, taking into account linguistic diversity and the contextual differences of the marine and inland sectors. This publication will be useful for fishworkers, fishworker organizations, researchers, policymakers, fish farmers, members of civil society and anyone interested in small-scale fisheries and livelihoods.

In 1989-1991, the U.S. Fish and Wildlife Service surveyed breeding populations of seabirds on the entire California coast. This study was sponsored by the Minerals Management Service in relation to outer continental shelf oil and gas leasing. At 483 nesting sites (excluding terns and skimmers in southern California), we estimated 643,307 breeding birds of 21 seabird species including: 410 Fork-tailed Storm-petrel (Oceanodroma furcata); 12,551 Leach's Storm-petrel (O. leucorhoa); 7,209 Ashy Storm-petrel (O. homochroa); 274 Black Storm-petrel (O. melania); 11,916 Brown Pelican (Pelecanus occidentalis); 10,037 Double-crested Cormorant (Phalacrocorax auritus); 83,394 Brandt's Cormorant (P. penicillatus); 14,345 Pelagic Cormorant (P. pelagicus); 888 Black Oystercatcher (Haemotopus bachmani); 4,764 California Gull (Larus californicus); 61,760 Western Gull (L. occidentalis); 2,838 Caspian Tern (Sterna caspia) (excluding southern California); 3,550 Forster's Tern (S. forsteri) (excluding southern California); 272 Least Tern (S. albifrons) (excluding southern California); 351,336 Common Murre (Uria aalge); 15,470 Pigeon Guillemot (Cepphus columba); 1,821 Marbled Murrelet (Brachyramphus marmoratus); 1,760 Xantus' Murrelet (Endomychura hypoleuca); 56,562 Cassin's Auklet (Ptychoramphus aleuticus); 1,769 Rhinoceros Auklet (Cerorhinca monocerata); and 276 Tufted Puffin (Fratercula cirrhata). The inland, historical or hybrid breeding status of American White Pelican (P. erythrorynchus), American Oystercatcher (H. palliatus), Heermann's Gull (L. heermanni), Ring-billed Gull (L. delawarensis), Glaucous-winged Gull (L. glaucescens) and Black Tern (Chlidonias niger) are discussed. Estimates for Gull-billed Tern (S. nilotica), Royal Tern (S. maxima), Elegant Tern (S. elegans) and Black Skimmer (Rhynchops niger) will be included in the final draft of this report. Overall numbers were slightly lower than reported in 1975-1980 surveys (summarized in Sowls et al. 1980. Catalog of California seabird colonies. U.S. Dept. Int., Fish Wildl. Serv., Biol. Serv. Prog., FWS/OBS 37/80). Recent declines were found or suspected for Fork-tailed Storm-petrel, Leach's Storm-petrel, White Pelican, Black Tern, Caspian Tern, Least Tern, Common Murre and Marbled Murrelet. Recent increases were found or suspected for Brown Pelican, Double-crested cormorant, California Gull, Western Gull, Forster's Tern and Rhinoceros Auklet. Similar numbers were found for other species or trends could not be determined without additional surveys, studies and/or more in-depth comparisons with previous surveys. The status of terns and skimmers in southern California has not yet been finalized.

定量重建地球生态系统的气候参数是当前国际古气候研究的目标之一. 自20世纪70年代以来, 尤其是在海洋学研究领域, 新技术的不断应用使得定量的古气候研究蓬勃发展. 相比之下陆地古气候参数的重建要困难得多, 陆地植物作为对环境的良好记录,一直备受重视. 近数十年来, 国际上广泛开展了利用植物材料定量研究气候的探索, 大量新的方法层出不穷. 德国科学家Mosbrugger和Utescher在1997年倡导的共存分析法(The Coexistence Approach)就是其中之一, 它依据现存最近亲缘类群原理以及植物分布与气候的关系原理, 找到化石植物群中各类群的现存最近亲缘类群对各气候参数的耐受范围; 并将各亲缘类群对同一气候参数的耐受范围叠加一起, 获得对该气候参数的共存区间, 用该区间作为对古气候参数的精确估测. 本文首先阐述在原文位于展开讨论的共存分析的理论基础——探讨植物分布与气候之间关系的耐受性理论. 并以此为指导, 对在该方法中气候台站的选用方法作了改进, 气象台站的选择应以植物的标本记录点为基础: 即使在某一特定的植物分布区内部也应该查看气象台站所在县级行政区域是否有该植物的标本采集信息, 并以此为依据来决定是否选用该气象台站的记录; 选用的气象台站的数量多寡应该以植物分布点的多少来决定. 以此为基础, 我们采用中国的植物分布与气象记录数据, 利用孢粉学的研究结果,定量重建了我国新生代三个地点的古气候参数, 结果如下: 1.内蒙古呼伦湖地区全新世初期气候 MAT: 4.4~10.2℃; MWMT: 22.9~24.1℃; MCMT: -18~-9.1℃; DT: 33.5~40.9℃; MAP: 354.3~686.7mm; MMaP: 103.8~191.9mm; MMiP: 2.7~7.3mm. 我们以扎赉诺尔地区的孢粉学研究为基础, 依据孢粉和盘星藻(Pediastrum Meyen)提供的环境信息并结合前人工作, 恢复了全新世初升温期的植被变化; 定量重建了10.4~10.2kaB.P.时的气候, 为全面理解呼伦湖地区的气候变化以及东亚的夏季风变化提供新的依据. 2.云南洱源上新世气候 MAT: 13.3~18.6℃; MWMT: 24.6~27.5℃; MCMT: 1.9~12.1℃; DT: 14.2~16.6℃; MAP: 619.9~1484.3mm; MMaP: 143.8~245.6mm; MMiP: 12.7~16.4mm. 该结果与羊邑、龙陵上新世古气候及三地的现代气候分析对比表明, 在上新世, 三地年均温符合纬向变化, 而降水量则基本一致. 在现代,洱源与羊邑在气候与植被上很相近, 且与上新世相差不大; 而龙陵地区则发生了显著的变化, 年均温比上新世低, 而降水量则大幅增加. 该变化指示了上新世以来作为青藏高原东部边缘的龙陵地区可能出现了地形的抬升. 3.吉林珲春始新世和中新世气候 始新世: MAT: 14.3~14.9℃; MWMT: 25~26.3℃; MCMT: 1.9~3.7℃; DT: 21.7~23℃; MAP: 797.5~1344mm; MMaP: 185.3~209.8mm; MMiP: 14.2~16.4mm. 中新世: MAT: 14.3~14.9℃; MWMT: 24.3~25.4℃; MCMT: 2.1~3.7℃; DT: 21.7~22.7℃; MAP: 658.7~817.7mm; MMaP: 158.9~174.6mm; MMiP: 7.4~7.6mm. 通过对两个时段的气候参数对比, 始新世时, 吉林珲春地区的气候属于北亚热带气候; 中新世时气候发生了改变, 归属于暖温带南部的气候, 改变了前人关于中新世也归属于被亚热带的认识, 这反映了我国东北部地区与全球新生代降温总趋势具有一定的同步性.

The National Oceanic and Atmospheric Administration (NOAA), in cooperation with the New Jersey Marine Sciences Consortium (NJMSC), hosted a workshop at Rutgers University on 19-21 September 2005 to explore ways to link the U.S. Integrated Ocean Observing System (IOOS) to the emerging infrastructure of the National Water Quality Monitoring Network (NWQMN). Participating partners included the Mid-Atlantic Coastal Ocean Observing Regional Association, U.S. Geological Survey, Rutgers University Coastal Ocean Observing Laboratory, and the New Jersey Sea Grant College. The workshop was designed to highlight the importance of ecological and human health linkages in the movement of materials, nutrients, organisms and contaminants along the Delaware Bay watershed-estuary-coastal waters gradient (hereinafter, the “Delaware Bay Ecosystem [DBE]”), and to address specific water quality issues in the mid-Atlantic region, especially the area comprising the Delaware River drainage and near-shore waters. Attendees included federal, state and municipal officials, coastal managers, members of academic and research institutions, and industry representatives. The primary goal of the effort was to identify key management issues and related scientific questions that could be addressed by a comprehensive IOOS-NWQMN infrastructure (US Commission on Ocean Policy 2004; U.S. Ocean Action Plan 2004). At a minimum, cooperative efforts among the three federal agencies (NOAA, USGS and EPA) involved in water quality monitoring were required. Further and recommended by the U.S. Commission on Ocean Policy, outreach to states, regional organizations, and tribes was necessary to develop an efficient system of data gathering, quality assurance and quality control protocols, product development, and information dissemination.

NOAA has a mandate to explore and understand deep-sea coral ecology under Magnuson-Stevens Sustainable Fisheries Conservation Act Reauthorization of 2009. Deep-sea corals are increasingly considered a proxy for marine biodiversity in the deep-sea because corals create complex structure, and this structure forms important habitat for associated species of shrimp, crabs, sea stars, brittle stars, and fishes. Yet, our understanding of the nature of the relationships between deep-corals and their associated species is incomplete. One of the primary challenges of conducting any type of deep-sea coral (DSC) research is access to the deep-sea. The deep-sea is a remote environment that often requires long surface transits and sophisticated research vehicles like submersibles and remotely operated vehicles (ROVs). The research vehicles often require substantial crew, and the vehicles are typically launched from large research vessels costing many thousands of dollars a day. To overcome the problem of access to the deep-sea, the Deep Coral and Associated Species Taxonomy and Ecology (DeepCAST) Expeditions are pioneering the use of shore-based submersibles equipped to do scientific research. Shore-based subs alleviate the need for expensive ships because they launch and return under their own power. One disadvantage to the approach is that shore-based subs are restricted to nearby sites. The disadvantage is outweighed, however, by the benefit of repeated observations, and the opportunity to reduce the costs of exploration while expanding knowledge of deep-sea coral ecology.

This cruise report is a summary of a field survey conducted along the continental shelf of the northeastern Gulf of Mexico (GOM), encompassing 70,062 square kilometers of productive marine habitats located between the Mississippi Delta and Tampa Bay, August 13–21, 2010 on NOAA Ship Nancy Foster Cruise NF-10-09-RACOW. Synoptic sampling of multiple ecological indicators was conducted at each of 50 stations throughout these waters using a random probabilistic sampling design. At each station samples were collected for the analysis of benthic community structure and composition; concentrations of chemical contaminants (metals, pesticides, TPHs, PAHs, PCBs, PBDEs) in sediments and target demersal biota; sediment toxicity; nutrient and chlorophyll levels in the water column; and other basic habitat characteristics such as depth, salinity, temperature, dissolved oxygen, turbidity, pH, CDOM fluorescence, sediment grain size, and organic carbon content. Discrete water samples were collected just below the sea surface, in addition to any deeper subsurface depths where there was an occurrence of suspicious CDOM fluorescence signals, and analyzed for total BTEX/TPH and carcinogenic PAHs using immunoassay test kits. Other indicators of potential value from a human-dimension perspective were also recorded, including presence of any vessels, oil rigs, surface trash, visual oil sheens in sediments or water, marine mammals, or noxious/oily sediment odors. The overall purpose of the survey was to collect data to assess the status of ecosystem condition and potential stressor impacts throughout the region, based on these various indicators and corresponding management thresholds, and to provide this information as a baseline for determining how such conditions may be changing with time. In addition to the original project goals, both the scientific scope and general location of this project are relevant to addressing potential ecological impacts of the Deepwater Horizon oil spill. While sample analysis is still ongoing, a few preliminary results and observations are reported here. A final report will be completed once all data have been processed.
