This data set contains a zipped file with 8 individual .csv files used to support the analysis of survival bottlenecks presented by Hinke et al.(2020), "Acute bottlenecks to the survival of juvenile Pygoscelis penguins occur immediately after fledging". Data include geographical position estimates from satellite telemetry studies on Adélie (Pygoscelis adeliae), chinstrap (P. antarctica), and gentoo (P. papua) penguins tracked from the Antarctic peninsula region, carcass counts from ship and beach surveys in the study region, fledgling weights, and battery voltage data from telemetry tags.
Data were collected from several penguin monitoring sites in the Antarctic peninsula region, the South Orkney Islands, and East Antarctica between 1977 and 2017 using traditional and autonomous methods.Traditional methods consisted of researchers conducting direct observations of penguins throughout the season to record information on egg laying, incubation, and brood/guard periods. Simultaneously, autonomous methods consisted of time-lapse cameras deployed at the penguin colonies to photographically record the same daily nesting activities throughout the season. Seabirds observed in this study are Adélie (Pygoscelis adeliae), chinstrap (P. antarctica), and gentoo (P. papua) penguins.
PICEAS (Pacific Islands Cetacean Ecosystem Assessment Survey) 2005 was an ecosystem survey in the U.S. Exclusive Economic Zone (EEZ) waters of Palmyra and Johnston Atoll and adjacent waters south of Hawaii where Hawaiian long-line fishing occurs.
This survey focused on two species of common dolphin: the short-beaked common dolphin, Delphinus delphis, and the long-beaked common dolphin, Delphinus capensis , off southern California, USA and Baja California, Mexico.
The CSCAPE 2005 cruise was a collaboration between the National Marine Fisheries Service (NMFS) and the National Marine Sanctuary (NMS) Program to assess the abundance and distribution of marine mammals and to characterize the pelagic ecosystem off the U.S. West Coast.
Fish larvae counts and standardized counts for larvae captured in CalCOFI icthyoplankton nets (primarily vertical [Calvet or Pairovet], oblique [bongo or ring nets], and surface tows [Manta nets]). Surface tows are normally standardized to count per 1,000 m3 strained. Oblique tows are normally standardized to count per 10 m2 of surface sampled. This table includes all tows by species, even if zero larvae were captured for the species, i.e., negative tows. The "Larvae Counts Positive Tows" table includes only tows where one or more larvae were captured for the species selected by the user.
An aerial monitoring program was conducted during the period 1962 - 2003 in cooperation with aerial spotters working for the commercial purse seine fleet. Flights were conducted throughout the year to estimate abundance of pelagic fishes off California and Baja California, Mexico. Measurements were recorded for each identifiable species in 10'-longitude by 10'-latitude blocks. Northern anchovy, (Engraulis mordax), Pacific sardine (Sardinops sagax), Pacific bonito (Sarda chiliensis), Pacific mackerel (Scomber japonicas), jack mackerel (Trachurus symmetricus) and Bluefin tuna (Thunnus thynnus orientalis) were the most commonly reported species.
