The trawl database contains multiple tables of data. The ‘haul’ table contains the location, date, time and depth of the trawl haul. The ‘catch’ table contains the numbers and weights of the taxa in each haul. The ‘length’ table contains the lengths of selected taxa in each haul. There is data for the eastern Bering Sea for 2008, 2010, 2012, and 2014. There is Gulf of Alaska trawl data from 1993 to 2015.

The data (Appendix 1) describe multiple micro samples from 40 specimens. The data set first provides specimen identification information: Specimen ID, estimated age, and AFSC RACE cruise number. Second, the data describes the milling and physical properties of each milled sampled, up to 42 samples per specimens: volume and mass. Finally, the data contain information and results from mass spectrometry analysis measuring d13C and d18O.

Annual growth increment patterns observed in the hard parts of many marine organisms are often related to factors in the physical environment, and investigators are increasingly using dendrochronology (tree-ring science) methods to explore these relationships. Dendrochronology techniques were applied to otolith growth increments in 3 flatfish species collected from the eastern Bering Sea: northern rock sole Lepidopsetta polyxystra, yellowfin sole Limanda aspera, and Alaska plaice Pleuronectes quadrituberculatus. Within each species, otoliths were visually crossdated to ensure that the correct calendar year was assigned to each growth increment. Growth-increment widths were measured in each otolith, crossdating was statistically checked, and a master chronology was generated for each species by averaging measurement time series after age-related growth declines had been removed. The 3 final chronologies spanned 18 to 20 yr and were significantly correlated with each other, indicating a high level of growth synchrony among species. Final chronologies were compared to annual and monthly climate variables, and were most strongly related to summertime eastern Bering Sea bottom temperatures.

Annual growth increment patterns observed in the hard parts of many marine organisms are often related to factors in the physical environment, and investigators are increasingly using dendrochronology (tree-ring science) methods to explore these relationships. Dendrochronology techniques were applied to the otolith growth increments of yellowfin sole Limanda aspera to determine the extent to which somatic growth and otolith growth are coupled. Otoliths were visually crossdated to ensure that the correct calendar year was assigned to each growth increment. Growth-increment widths were measured in each otolith, crossdating was statistically checked, and a master chronology was generated by averaging measurement time series after age-related growth declines had been removed. The final chronology spanned 43 yr and was significantly related to Bering Sea bottom temperature and sea surface temperature. The relationship between otolith growth and somatic growth was explored using regression analysis. Population-wide otolith anomalies were found to be significantly related to population-wide anomalies in body size, as indexed by fish weight-length ratios.

Ryan Nichols (FBSAB LHP) collected this data set and it contains only information pertaining to Hypothordus quernus, Hapu'upu'u, Hawaiian grouper. It contains date, location, fish length (total), fish weight, otolith weight (grams), otolith length (mm), otolith width (mm) age group, and which sagittal was aged (right or left).

Data collected on this cruise included the following: We conducted a juvenile fish and benthic fish prey survery in the eastern Bering Sea (61 3-meter beam trawls, 64 modified tucker epibenthic plankton sled tows, 54 van veen benthic grab collections).

The data set focuses on the diets of young of the year Gadus chalcogrammus from the Eastern Gulf of Alaska and the South Eastern Bering Sea. Diet data is available in select years and locations for year one Gadus chalcogrammus and juvenile Mallotus villosus, Thaleichthys pacificus, Lepidopsetta polyxystra, Limanda aspera, Gadus chalcogrammus, Atheresthes stomias, Hippoglossoides elassodon and Atheresthes evermanni. Diet data currently in EcoDAAT are from 1993-2010. The early 1990’s ,except for 1993, are focused on transects extending of the Pribilof islands. From 2000-2010 sampling occurred in the Eastern Gulf of Alaska, except for 2008 when sampling occurred in the South Eastern Bering Sea. Currently there are 166 prey taxa or groups identified within the diets of all fish. The majority of identifications being: large copepod, small copepod, and euphausiid.

Data set includes port samples of reef fish species collected from commercial and recreational fishery landings in the U.S. South Atlantic (NC - FL Keys). The data set serves as an inventory of samples stored at the NMFS Beaufort Laboratory as well as final processed data. Information that may be inlcuded for each sample is trip level information, species, size meansurements, age, sex and reproductive data.

The spiny dogfish (Squalus suckleyi, formerly Squalus acanthias, Ebert et al. 2010) is a small, long-lived and slow-growing shark, which is vulnerable to overfishing. Current methods for aging spiny dogfish are based on reading annuli from dorsal fin spines, which erode and may break. For the past 30 years, scientists have used an exponential relationship between the diameter of the spine and the number of annuli to estimate the number of missing annuli. Coupled with between-reader imprecision (CV = 19%), errors in estimation of worn annuli introduce uncertainty and bias into the aging process, resulting in large confidence intervals and imprecise growth, mortality, and recruitment estimates necessary for stock assessments. Using spines and vertebrae collected from spiny dogfish in the Gulf of Alaska, we aged the spines using conventional methods and vertebrae using the vertebral method. Data presented here includes the sample collection information, raw spine and vertebrae age read data and final annuli counts calculated from the multiple reads. This project was funded by NPRB and was a collaborative work between: AFSC age and growth lab, WA Dept Fish and Wildlife, NWFSC age and growth lab, Dr. Walter Bubley and UAF, and Bechtol Research

A total of 105 stations were occupied. There were two sample grids (southeast Alaska and Yakutat Bay) and two transects in the vicinity of Kayak Island. At each station we sampled using paired 20 and 60 cm Bongo frames (150 and 500 micron mesh nets, respectively) and a Sameoto neuston sampler (500 micron mesh net) to estimate the abundance of zoo- and ichthyoplankton. A SeaBird SeaCat (SBE 19 plus) was used with the bongo frames to determine the depth of the samplers in real time and to measure temperature and conductivity. At a few selected stations depth-stratified plankton were obtained with a 1 meter squared MOCNESS (500 micron mesh nets) and at other selected stations microzooplankton were sampled with vertical tows of a CalVET net (53 micron mesh).
