This coastal monitoring study in the northern region of southeastern Alaska, known as the Southeast Coastal Monitoring Project (SECM), was initiated in 1997 and repeated from 1998 to 2006 (Orsi et al. 1997, 1998, 2000, 2001, 2002) to develop our understanding of the relationships between annual time series of biophysical data and stock-specific information.

CTD data was collected in conjunction with juvenile salmon studies in the Gulf of Alaska from 1997-2006 by the Southeast Coastal Monitoring Project.

Laboratory experiments were carried out to characterize plankton infection dynamics and extracellular metabolites over an infection cycle in two parasite-host pairings. Data reported here are cell concentrations, percent of host infected, and bulk DOC concentrations measured daily over an infection cycle (four days) that coincides with collection of extracellular metabolites for analysis via liquid chromatography-mass spectrometry. Separate experiments were performed for two strains of the parasite Amoebophyra sp. (4390 and 4401) that infected the same host dinoflagellate species, Scrippsiella acuminata. Metabolomics data collected from these experiments will be available on MetaboLights (MTBLS11219). cdm_data_type=Other Conventions=COARDS, CF-1.6, ACDD-1.3 doi=10.26008/1912/bco-dmo.962736.1 infoUrl=https://osprey.bco-dmo.org/dataset/962736 institution=BCO-DMO sourceUrl=(local files)

The Gulf of Alaska is a highly seasonal environment characterized by an order-of-magnitude increase in copepod biomass in the photic zone between winter and spring. The study focused on copepod recruitment to characterize species-specific naupliar production. Concurrent environmental monitoring included taxonomic identification of microplankton using microscopy. cdm_data_type=Other Conventions=COARDS, CF-1.6, ACDD-1.3 doi=10.26008/1912/bco-dmo.954189.1 Easternmost_Easting=-149.3583 geospatial_lat_max=60.025 geospatial_lat_min=60.025 geospatial_lat_units=degrees_north geospatial_lon_max=-149.3583 geospatial_lon_min=-149.3583 geospatial_lon_units=degrees_east geospatial_vertical_max=280.0 geospatial_vertical_min=50.0 geospatial_vertical_positive=down geospatial_vertical_units=m infoUrl=https://osprey.bco-dmo.org/dataset/954189 institution=BCO-DMO Northernmost_Northing=60.025 sourceUrl=(local files) Southernmost_Northing=60.025 Westernmost_Easting=-149.3583

Using recent advances in indirect genetic methods applied to both adult plants and dispersed seeds, we find that the mean seed dispersal in a threatened marine foundation plant (the seagrass Zostera marina) is approximately 100-200 meters. We documented strong phenotypic variation and genome-wide differentiation among plants separated by less than the spatial scale of mean realized dispersal, which suggests genetic isolation by environment in response to depth-related environmental gradients. Within all meadows, the ratio of effective to census size (or Ne/Nc) approximated 0.1%, indicating that a fraction of existing plants provides the genetic variation to allow adaptation to environmental change. The SRA dataset at NCBI contains the raw sequencing reads that were used to create genotypes and genotype likelihoods. cdm_data_type=Other Conventions=COARDS, CF-1.6, ACDD-1.3 doi=10.26008/1912/bco-dmo.958698.1 Easternmost_Easting=-70.65518 geospatial_lat_max=42.59676 geospatial_lat_min=42.41902 geospatial_lat_units=degrees_north geospatial_lon_max=-70.65518 geospatial_lon_min=-70.91759 geospatial_lon_units=degrees_east infoUrl=https://osprey.bco-dmo.org/dataset/958698 institution=BCO-DMO Northernmost_Northing=42.59676 sourceUrl=(local files) Southernmost_Northing=42.41902 Westernmost_Easting=-70.91759

Sediment pore waters were determined in cores collected at several stations off the coast of California: at a site in Santa Barbara Basin ('SBB'; latitude: 34.223, Longitude: -119.986; water depth, 590 m); Catalina Basin ('Cat'; latitude: 33.301, longitude: -118.6; water depth, 1310 m); and two sites off the coast of central California south of Monterey Bay; site 'K' (latitude 35.375, longitude -121.501, water depth, 1000 m) and site 'D' (latitude 36.113, longitude: -122.186, water depth, 1440 m). The Cat cores were collected in June 2019, while the site K and D cores were collected in December 2020. Pore waters were collected either using rhizon samplers or by centrifugation of sectioned sediments. Pore water samples were analyzed for alkalinity on-board the ship, while other analyses were returned to the shore-based lab at Old Dominon University (ODU) where they were analyzed. These samples were collected as part of a larger project examining deaminated peptides and organic matter cycling in the sediments at these sites. cdm_data_type=Other Conventions=COARDS, CF-1.6, ACDD-1.3 doi=10.26008/1912/bco-dmo.959247.1 Easternmost_Easting=-118.6 geospatial_lat_max=36.1126 geospatial_lat_min=33.3005 geospatial_lat_units=degrees_north geospatial_lon_max=-118.6 geospatial_lon_min=-122.1861 geospatial_lon_units=degrees_east infoUrl=https://osprey.bco-dmo.org/dataset/959247 institution=BCO-DMO Northernmost_Northing=36.1126 sourceUrl=(local files) Southernmost_Northing=33.3005 Westernmost_Easting=-122.1861

While the recently decimated predatory sea star, Pycnopodia helianthoides, may support kelp forests by consuming herbivorous sea urchins, less is known about their non-consumptive effects. We conducted a field experiment in three replicate sea urchin barrens in Sitka Sound, Alaska in February of 2023, where we deployed pre-weighed Macrocystis pyrifera blades at discrete distances on four metre radial cables from caged adult P. helianthoides and control cages and reweighed after 24 hours. Our results suggest the chemical cue of P. helianthoides elicits a localised, species-specific landscape of fear that suppresses grazing, and that the non-consumptive effects of P. helianthoides on sea urchin behaviour may be important for kelp restoration. cdm_data_type=Other Conventions=COARDS, CF-1.6, ACDD-1.3 doi=10.26008/1912/bco-dmo.942729.1 Easternmost_Easting=-135.255 geospatial_lat_max=57.036 geospatial_lat_min=57.033 geospatial_lat_units=degrees_north geospatial_lon_max=-135.255 geospatial_lon_min=-135.28 geospatial_lon_units=degrees_east infoUrl=https://osprey.bco-dmo.org/dataset/942729 institution=BCO-DMO Northernmost_Northing=57.036 sourceUrl=(local files) Southernmost_Northing=57.033 Westernmost_Easting=-135.28

This dataset is part of a field study examining the effect of diel oxygen cycling on faunal activity, and in turn sediment oxygen demand. The field experiment used in situ flow-through benthic chambers to measure oxygen consumption, as described in the methods paper Gadeken et al 2023. The chambers were deployed and retrieved in three ~24 hour deployments in a shallow subtidal area of Bon Secour Bay in Mobile Bay, AL, in August 2021. This dataset contains sediment characteristic information from three cores taken within 10m of the deployment location. cdm_data_type=Other Conventions=COARDS, CF-1.6, ACDD-1.3 doi=10.26008/1912/bco-dmo.940989.1 Easternmost_Easting=-87.8941 geospatial_lat_max=30.23948 geospatial_lat_min=30.23948 geospatial_lat_units=degrees_north geospatial_lon_max=-87.8941 geospatial_lon_min=-87.8941 geospatial_lon_units=degrees_east geospatial_vertical_max=7.5 geospatial_vertical_min=0.5 geospatial_vertical_positive=down geospatial_vertical_units=m infoUrl=https://osprey.bco-dmo.org/dataset/940989 institution=BCO-DMO Northernmost_Northing=30.23948 sourceUrl=(local files) Southernmost_Northing=30.23948 Westernmost_Easting=-87.8941

Initial positions of drifters deployed from 1995 to 1999 in support of the U.S. GLOBEC Georges Bank program. For drifter tracking, see the 'drifter_tracks' dataset.

Notes:
¹Drifters named with a leading 'g' were generally deployed in US terriorial waters and drifters identified with a leading 'n' were deployed in Canadian Waters by Peter Smith from the Bedford Institute of Oceanography (BIO). Also, drifter types containing a gps system reported positions every 30 minutes.

²'inst' parameter is a combination of: Manufacturer code (se = Seimac, cw = Clearwater, met = MEtocean, to = Technocean) + Center depth of drogue (10 or 40 meters) + Shape of drogue (W = wide, versus a square drogue) + Presence of gps system (gps)

Results of laboratory experiments examining growth and CO2-fixation rate of two isolates of Crocosphaera watsonii, WH0401 and WH0402, in response to different pCO2 levels and light intensities. Isolates of C. watsonii, a unicellular marine N2-fixing cyanobacterium, were obtained from the western tropical Atlantic Ocean and cultured in the laboratory. WH0402 was grown at two concentrations of CO2 (air and 750 ppm) at five light intensities (18-300 umol quanta m-2 s-1). WH0401 was grown at three concentrations of CO2 (190, air, and 750 ppm) under the same range of light intensities (however WH0401 could not be acclimated to 18 or 50 umol quanta m-2 s-1).
