The objectives of this cruise are to conduct an ichthyoplankton survey and process oriented studies in the region between the Shumagin Islands to Shelikof Strait so that we may estimate the abundance, transport, and factors influencing the survival of young walleye pollock larvae. We will also occupy stations on Line 8 to continue our 23-year time series of environmental and biological conditions in Shelikof Strait.

The primary objective of this cruise will be the recovery and deployment of moorings in the Gulf of Alaska and Bering Sea.

Continue acquisition of long-term biological and physical time series. Recover and deploy moorings at FOCI site 2 and site 3. Deploy satellite-tracked drifting buoys.

We will conduct an ichthyoplankton survey in the waters contiguous to Kodiak Island, Alaska. This work is needed to describe larval fish assemblages on the shelf and slope in winter, and to study the transport and early life history of larval fishes, particularly the feeding and zooplankton prey of capelin (Mallotus villosus) and Pacific sand lance (Ammodytes hexapterus). Data on physical characteristics of the water column will also be collected.

The primary objective of this cruise was to conduct bottom trawl sampling in the head of Bering Canyon to collect ripe adult arrowtooth flounder (ATF) and conduct deep 60 cm bongo plankton tows to collect their eggs and establish their appearance so they can be identified in the future with confidence in plankton samples. The secondary objective was to collect CTD data and 20 cm bongo, chlorophyll, and nutrient samples on line "D" of the "Unimak Box".

Fisheries-Oceanography Coordinated Investigations (FOCI) is an effort by National Oceanic and Atmospheric Administration (NOAA) and associated academic scientists. FOCI's goal is to understand the effects of abiotic and biotic variability on ecosystems of the North Pacific Ocean and Bering Sea in order to discern the physical and biological processes that determine recruitment variability of commercially valuable finfish and shellfish stocks in Alaskan waters. We will focus our efforts on the physical, chemical and biological processes occurring in particular areas of this region. These include: several troughs of differing size, banks, the area near Kennedy - Stevenson Entrances, as well as one of the large offshore eddies, that typically impact this area between April and July and contribute to on and offshore fluxes.

To recover and deploy several oceanographic moorings. To complete Conductivity, Temperature, and Depth (CTD) profiler casts, California Cooperative Oceanic Fisheries Investigation (CalCOFI) Vertical Egg Tow (CalVET) and Marine Assessment Monitoring and Prediction (MARMAP) Bongo tows near the mooring sites and along the 70-meter isobath in the Bering Sea.

This dataset contains bathymetry (water depth), ship's heading, ship's speed and position data collected during the Nella Dan Voyage 1 1985-86. This was a marine science voyage departing Hobart, visiting Heard Island, beset at Amundsen Bay and returning to Hobart. Data are available online via the Australian Antarctic Division Data Centre web page (or via the Related URL given below). For further information, see the Marine Science Support Voyage Report at the Related URL below.

These data were collected on voyage 3 of the RSV Nuyina in the 2024/2025 season. The voyage was colloquially known as the "Denman Marine Voyage", as it operated in the vicinity of the Denman Glacier. Conductivity, Temperature and Depth (CTD) data were collected at various CTD stations throughout the voyage. Every time the CTD is ready to be deployed into the water and profile the water column, a folder is created under the name ‘cast_#’, where ‘#’ is a number. A number is assigned each time the CTD was turned on. There are a few instances when the CTD was turned on, but there was an issue, and the profiling did not occur. A number was still assigned and a cast folder created. Each ‘cast_#’ has several folders: docs, ladcp, proc and raw. - docs: ‘docs’ stands for ‘documents’. Here the logsheets with the information relevant to the CTD deployment, locations, time of cast, voyage name, depths at which Niskin bottles are fired, variables to be measured with the seawater collected at each bottle, and relevant information on toolbox, and rosette set-up are found. - ladcp: raw lower Acoustic doppler current profiler (ladcp) data - proc: ‘proc’ stands for ‘processed’ data. Raw data from SeaBird is shown in different formats and various snapshots of the data are also saved. o Hex: data format from Seabird911 o Other files from seabird: bl (information related to the firing of niskin bottles), and hdr and XMLCON (configuration files) o csv: same as above but in a format that can be read by text readers such as note app. Note that this is not the same as ‘processed data’ where the data goes through a series of steps and calibrations. o Cnv: this contains the data after the first data processing step according to Seasave software. It contains header with information on location, UTC time, and information on how the Seabird911 was configured, including the calibration coefficients of all the instruments.
