The data presented here represent the sightings of cetaceans on whale watch cruises with CRESLI on vessels of the Viking Fleet in waters off Montauk Point, up to ~30 nautical miles during the months of July through early September, from 2009 to the present. The following species were observed, recorded, and photographed: fin whales (Balaenoptera physalus), minke whales (Balaenoptera acutorostrata), humpback whales (Megaptera novaeangliae), North Atlantic right whales (Eubalaena glacialis), Short-beaked common dolphins (Delphinus delphis), Bottlenose dolphins, Western North Atlantic Offshore Stock (Tursiops truncatus), Western North Atlantic Northern Migratory Coastal Stock (Tursiops truncatus). These data were collected during local (6-8 hour) whale watching trips conducted by the Viking Fleet and CRESLI. Trips originated from Montauk Harbor in Montauk, New York and occurred regularly from 1997-2002 and again from 2009 - present, during July, August and early September. The data were collected during efforts to gather information about the distribution, abundance, habitat use and site fidelity, and behavior of cetaceans in the waters around Montauk, New York. The on-board public were educated, and volunteers were involved in collecting data, as citizen scientists.

This project will collect and effectively manage strategies for whale watching activities at home and abroad, interview stakeholders related to whale watching activities, take stock of the current issues and controversies surrounding whale watching behaviors, hold workshops or meetings, formulate whale watching regulations that can be incorporated into existing laws and regulations, and provide feasible management practices and suggestions. In addition, through the design of whale-watching promotional materials, the recording of the results video, the implementation of whale-watching education training, and the promotion activities for the public, it aims to gradually reduce the human impact of whale-watching activities and achieve sustainable development of both the whale-watching industry and our country's cetacean resources through feasible whale-watching regulations.

Three marine mammal observers conducted visual surveys along transect lines sampled during the Alaska Fisheries Science Center (AFSC) / National Oceanic and Atmospheric Administration (NOAA) walleye pollock stock assessment cruise from 1 June to 30 July 2008. Whale sightings included fin (78), humpback (47), minke (7), sei (1), gray (1), sperm (4), killer (35), and Baird's beaked (2) as well as harbor (56) and Dall's (172) porpoise. Data from this project will be combined with oceanographic and prey data to analyze habitat selection, submitted to project B92 (Top predator hotspot persistence), and used to investigate if cetacean sightings match predator-prey fields predicted by the Forage and Euphausiid Abundance in Space and Time (FEAST) model (M.47).

Time–area closures have been widely used in fisheries management to prevent overfishing and reduce the bycatch of protected species. Due to quota overages and concerns about entanglement of federally protected North Atlantic right whales Eubalaena glacialis, the commercial harvest of Black Sea Bass Centropristis striata using pot gear has been prohibited in the southeastern United States in winter since 2009. Following the rebuilding of the Black Sea Bass stock and a change to the start date of the fishing year, the South Atlantic Fishery Management Council (SAFMC) increased the commercial annual catch limit (ACL) and is considering twelve alternatives to the pot gear closure that would revise the timing and/or spatial extent of the closure. Changes to this closure could affect the annual catch of Black Sea Bass and increase the risk of right whale entanglement in pot gear. Using historical fishing effort, landings, and right whale sightings data, we projected Black Sea Bass landings and the relative risk of right whale entanglement for each closure alternative, expressed in relative risk units (RRU). We predict that the ACL would be caught, resulting in an in-season closure for most of the proposed SAFMC closure alternatives. The relative risk of entanglement, estimated from the spatial and temporal overlap of Black Sea Bass pot gear fishing effort and right whale relative abundance, was lower for some alternatives than for others, and the relative differences between alternatives were consistent among uncertainty scenarios. The SAFMC’s preferred alternative is projected to result in a relatively low increase in risk to North Atlantic right whales (3–15 RRU off North Carolina and 1–12 RRU off Florida–South Carolina). This framework demonstrates the use of temporally dynamic spatial overlays in assessing the impacts of time–area closures with multiple objectives. Received April 23, 2015; accepted January 15, 2016

This 1993 line-transect survey was designed to make abundance estimates of the northern stock of common dolphin, Delphinus delphis, in the eastern Pacific. This stock of dolphin is taken in the tropical tuna fishery. The index of relative abundance for this stock, computed from sightings on tuna vessels, has declined substantially in the last decade. However, because tuna vessels cover only the southern portion of the stock's range, the declines in the index may be due to a northward shift in distribution, rather than an actual decline in abundance. The 1993 survey was designed to produce the first range-wide estimates of abundance for the northern common dolphin and its recently described congener, Delphinus capensis. This survey was conducted by the NOAA Southwest Fisheries Science Center aboard NOAA Ships McArthur and David Starr Jordan for a combined total of approximately 32,000 kilometers surveyed from late July to early November 1993. This dataset provides the time-date and geographical coordinates, by species/stock, of all cetaceans detected during the survey, as well as the daily and intra-daily start and end points of the line-transect survey.

Sightings were used, as appropriate, to inform estimation of the line-transect parameters, where f(0) relates to the detection function, E(s) is the mean cluster size, and ni/Li is the stock-specific encounter rate.Group size is either the geometric mean of the best estimates of the observers or the sum of the best estimates of subgroup size.Sightings were assigned to one of three stocks: the pelagic, Northwestern Hawaiian Islands (NWHI), or main Hawaiian Islands (MHI) based on genetics (G), location (L), photo-identification (P), proximity (X), or tagging (T).

Abstract: The 2009 "Ecosystem Survey of Delphinus Species" research survey focused on the two species of common dolphin, Delphinus delphis and D. capensis, found off southern California, USA, and Baja California, Mexico. The primary objective was to provide information to improve conservation and management plans for these species. The project used a multidisciplinary approach. For both Delphinus species, data were collected to estimate abundance, pregnancy and birth rates, timing of reproduction, gene flow, and contaminant concentrations. Oceanographic data were collected to characterize habitat, and data on distribution and abundance of seabirds, prey fishes, and squids were collected to further characterize the ecosystem in which these dolphins live. Photographs of dolphin schools were taken from a NOAA Twin Otter aircraft while the survey was being conducted. The aerial photographs will provide count and measurement data to calibrate observer estimates of school size and to estimate timing of reproduction and birth rates. This research will facilitate understanding population demography of these species in an ecosystem framework. Essential information about the primary focal species, D. capensis, will greatly increase our knowledge about this coastal species and the geographic extent of a Mexico-U.S. transboundary stock.
