National Parks

The National Parks dataset is frequently updated by the National Park Service (NPS) and is part of the U.S. Department of Transportation (USDOT)/Bureau of Transportation Statistics (BTS) National Transportation Atlas Database (NTAD). This dataset depicts National Park Service boundary data that was created by the Land Resources Division. NPS Director's Order #25 states: "Land status maps will be prepared to identify the ownership of the lands within the authorized boundaries of the park unit. These maps, showing ownership and acreage, are the 'official record' of the acreage of Federal and non-federal lands within the park boundaries. While these maps are the official record of the lands and acreage within the unit's authorized boundaries, they are not of survey quality and not intended to be used for survey purposes." As such this data is intended for use as a tool for GIS analysis. It is in no way intended for engineering or legal purposes.

Results of 2012 Pollock Acoustic-Trawl Survey Bering Sea- DY1207

Eastern Bering Sea shelf walleye pollock (Theragra chalcogramma) midwater abundance and distribution were assessed from Bristol Bay in the United States, to Cape Navarin, Russia, between 7 June and 10 August 2012 using acoustic-trawl techniques aboard the NOAA ship Oscar Dyson. Most of the pollock biomass in the U.S. exclusive economic zone (EEZ) was distributed between the Pribilof Islands and Cape Navarin, between roughly the 80 m and 200 m isobaths. Estimated pollock abundance in midwater (between 16 m from the surface and 3 m off bottom) in the U.S. EEZ portion of the Bering Sea shelf was 1.843 million metric tons (t), lower than in 2010 (2.323 million t) but higher than in 2009 or 2008 (0.924 million t, and 0.997 million t, respectively). Pollock biomass east of 170Â° W was 0.279 million t, the predominant length mode was 47-48 cm, and most ages ranged between 4 and 7 years. In the U.S. waters west of 170Â° W, pollock biomass was 1.563 million t (65.4% of total shelf-wide biomass), and dominant modal lengths were 23, 38, and 30 cm, corresponding to pollock aged 2, 4, and 3 years, respectively. In Russia (0.550 million t, 23% of total biomass), modal lengths and ages were similar, though generally smaller and younger than those in the U.S. waters west of 170Â° W. Vertical distribution analyses indicated that whereas 80-90% of the adults were within 50 m of the bottom only about 60% of the juveniles were observed in that depth layer. Results of a paired (midwater-bottom) trawl efficiency comparison project are presented. The preliminary spatial distribution of the euphausiid abundance index is presented, but analyses are still in progress.

AFSC/RACE/MACE: 2019-2020 Salmon and Pollock Object Detection

This dataset contains the annotated data, object detection models, and video data used to fine-tune and evaluate object detection models for salmon and pollock detection in videos collected in a commercial pollock trawl in Alaska. The annotated data contains track annotations for all Pacific salmon (Oncorhynchus spp.) and walleye pollock (Gadus chalcogrammus) present and frame level annotations that describe the trawl and background conditions. The annotated data is composed of 11,572 salmon and 73,394 pollock annotations from 16,989 video frames that came from 184 video clips. Five-fold cross validation was used to evaluate EfficientDet D2 and YOLO11n object detection models, and this dataset includes all of these models and a single-class, salmon-only YOLO11n model. In addition to the annotated video frames that are provided as images, videos from three fishing tows that were not annotated are included with their respective YOLO11n detections. These three fishing tows were used to further evaluate the object detection performance of the best performing pollock and salmon model and the salmon-only model.

AFSC/RACE/MACE: Results of 2009 Pollock Acoustic-Trawl Survey Bering Sea- DY0909

Eastern Bering Sea shelf walleye pollock (Theragra chalcogramma) abundance and distribution in midwater were assessed between 9 June and 7 August 2009 using acoustic-trawl techniques aboard the NOAA ship Oscar Dyson. The survey also assessed walleye pollock in the Cape Navarin area of Russia.  Results showed that ocean conditions were cold in 2009, as in the previous three years, compared to 2001-2005. Fewer pollock were observed east of 170Â¿W than in 2008, and a larger percentage of those were inside the Steller sea lion Conservation Area (SCA) than outside the SCA (79% in 2009, 70% in 2008).  The majority of the pollock biomass in the U.S. Exclusive Economic Zone (EEZ) was located to the west and northwest of the Pribilof Islands between the 100 m and 200 m isobaths. Estimated pollock abundance in midwater (between 16 m from the surface and 3 m off bottom) in the U.S. EEZ portion of the Bering Sea shelf was 8.08 billion fish weighing 0.924 million metric tons (t); in the Russian EEZ, there were 9.67 million fish weighing 0.005 million t (0.6% of the total midwater biomass). East of 170Â¿W, (9.6% of total biomass) the predominant length mode was 55 cm both inside and outside of the SCA. In the U.S. west of 170Â¿W (89.8% of total biomass) dominant modal lengths were 13, 31, and 23 cm, respectively.  In Russia, modal lengths were 43, 51, and 29 cm, with proportionally more adults and fewer juveniles than in the adjacent western U.S. EEZ. Age results indicated that inside the U.S. EEZ, juvenile walleye pollock (ages-1, -2, and -3) were dominant numerically (64%, 10%, and 21%, respectively) and represented 63% of the total biomass. Adult pollock (ages 4+) totaled 6% of the population numerically and 37% of the total biomass.  Vertical distribution analyses indicated that 93% of adult biomass was within 40 m of the seafloor.  Juveniles were found both near the seafloor and higher in the water column; 17% of juvenile biomass was within 50 m of the surface. Three dimensional size and shape patterns of the juveniles are described using data collected with a calibrated multibeam sonar, and variability in these patterns are explored as a function of ontogeny. Finally, a new euphausiid index of abundance computed from backscatter at 4 frequencies (18, 38, 120, and 200 kHz) is described.

AFSC/RACE/MACE: Results of 2014 Pollock Acoustic-Trawl Survey Bering Sea- DY1407

Eastern Bering Sea shelf walleye pollock (Gadus chalcogrammus) midwater abundance and distribution were assessed from Bristol Bay in the United States, to Cape Navarin, Russia, between 12 June and 13 August 2014 using acoustic-trawl survey methods aboard the NOAA ship Oscar Dyson. Water column temperatures were warm in 2014 compared with the cold temperatures of the past several survey years (2006-2012). Most walleye pollock biomass was distributed relatively evenly across the shelf from a region north of Unimak Island to Navarin Canyon, between roughly the 50 m and 1,000 m isobaths. Estimated pollock biomass in midwater (between 16 m from the sea surface and 3 m off bottom) in the U.S. EEZ portion of the Bering Sea shelf was 3.439 million metric tons (t), nearly twice the 2012 estimate  (1.843 million t) and the highest that has been observed since 2002. Pollock biomass east of 170Â° W was 1.425 million t (40% of the total shelf-wide), with 2-year-old pollock (26 cm modal fork length (FL)) comprising 55% of that biomass. Pollock biomass in U.S. waters west of 170Â° W was 2.013 million t (57% of total shelf-wide biomass), consisting primarily of pollock aged 1, 2, and 4-6 years (15, 26, and 38 cm dominant modal FL, respectively). Two-year-old pollock were more abundant east than west of 170Â° W and contributed to an eastward shift in distribution of U.S. pollock biomass compared with recent years. Estimated numbers of 2-year-old pollock also surpassed the numbers estimated for the strong 2008 year class in 2010, although the 2008 year class was still evident in the population. In Russia (104 thousand t, 3% of total biomass), primarily 4-year-old fish (38 cm modal FL), were observed, with proportionally fewer 1- and 2-year-olds than observed west of 170Â° W in the United States. The preliminary spatial distribution of euphausiid backscatter is presented, but analyses are still in progress
