An observational instrument array consisting of three Acoustic Doppler Current Profilers, six S4 Vector Averaging Current Meters (four of which were capable of wave measurements) one SeaPac 2100 Wave Gauge and four Water Level Recorders was deployed in a section of Ningaloo Reef for a period of fourteen days in November/December 1997. In addition a Waverider buoy was deployed well offshore and approximately 2.6 nautical miles north of the study region. The study site was chosen to fulfil two criteria: 1. the reef system had to be typical of the other reefs in the area: a series of reefs running approximately parallel to the coast separated by deep, narrow channels, and separated from the coast by wide lagoons open at both the north and south ends. 2. the area had to be sufficiently small to allow adequate coverage by the observational instrument array. The study location consisted of two reefs, each approximately 1km long, separated by a 100m wide channel. A shallow, 500m wide lagoon separated the reefs from the beach. Both reef faces had slopes of approximately 1 to 25 and rose from a depth of 10m to between 0m and 1m on the reef top. Instrument locations were chosen to observe all physically significant, short-term oceanographic processes that occur in, and influence the study region. Bathymetry data was also recorded using a downward looking Acoustic Doppler Current Meter mounted on the transom of a small boat and a DGPS positioning system. Meteorological data was obtained from the AIMS automatic weather station at the Milyering Visitor Centre, 30km south of the study region. The Ningaloo Reef study was undertaken to obtain a comprehensive dataset on the physical oceanographic processes that influence the circulation and flushing of the reefs in the Ningaloo region. Data obtained will be utilised to verify theoretical and numerical models of these oceanographic processes, such that these models can be generically applied to the Ningaloo Reef region as a whole. Instruments were deployed as follows: (a) An S4 current meter with an internal water level sensor was located in the northern entrance to the northern lagoon (Site 1) to measure flow into and out of the lagoon from the north. (b) An S4 current meter and Water Level Recorder (tide gauge) were located in the southern entrance to the southern lagoon (Site 2) to measure flow into and out of the lagoon from the south. (c) An S4 Current meter/Wave gauge was deployed in the channel between the two reefs (Site 3) to observe flow through this entrance. (d) A Water Level Recorder (tide gauge) was located within the lagoon, but in line with the channel between the two reefs (Site 4), to provide water level data within the lagoon relative to the water levels observed at both the northern and southern entrances. (e) Two Water Level Recorders (tide gauges) and two Acoustic Doppler Current Profilers were located In the deeper water immediately seaward of both the Northern (Site 5) and Southern (Site 6) reefs, to observe the water level and current structure in front of the reefs, and give some indication of the flow of water towards the reef front. (f) Current meter/Wave gauges were deployed near the reef break (Site 7) and slightly landward of the reef break (Site 8) of the northern reef and near the reef break (Site 9) and slightly landward of the reef break (Site 10) of the southern reef, to observe flow and wave height over the reef top. (g) A Waverider buoy was deployed offshore (Site 11) to observe swell incident on the study area.

Two RD Instruments Acoustic Doppler Current Profilers (ADCP) and a Sontek Acoustic Doppler Profiler (ADP) were deployed at the front of the northern reef and the southern reef during the Ningaloo Reef Circulation Study.Deployment details:Site 5 (Deployment 1): ADCP S/N 0412: -21.8076, 114.082133 (Front of northern reef)Deployed 28/11/97: Recovered 4/12/97.

These data are a component of the project 'Ningaloo Reef Circulation Study, Western Australia (1997)'.

This data is the output from processing of the Simrad EQ60 single beam sonar data collected in Ningaloo Marine Park (in 2007 and 2008) organised by Australian Institute of Marine Science (AIMS). CMST have developed Matlab code to read and process data obtained with the Simrad EQ60 to calculate depth. For one section (2008 North) the water column acoustic parameters: Nautical Area Scattering Coefficient (NASC) and the mean Volume Scattering Strength (Sv) were also calculated. Depth, E1 and E2 data collected 2006-2008 were also combined into one dataset. Data were interpolated into 50m grids using Kriging. This survey was undertaken to provide a) improved broad scale bathymetic data for Ningaloo and b) as a tool for the identification of areas of broad scale bathymetric and topographical interest in areas with different levels of protection within the Marine Park. Single beam data allows broad scale the characterization and classification of the seafloor in terms of geomorphological structure. This is relevant to the distribution of benthic habitats and help understand the spatial and temporal distribution of the deep water marine environment of NMP. The combination of topography and textural surfaces provide an excellent reference dataset for research and management of the NMP This data includes and builds upon the 2006 data set "Single beam acoustic surveys in Ningaloo Marine Park, Western Australia (WAMSI Node 3 Project 1 Subproject 3.1.1)"

2013 Fall CalCOFI. The California Cooperative Oceanic Fisheries Investigations (CalCOFI) are a unique partnership of the California Department of Fish and Wildlife, NOAA Fisheries Service and Scripps Institution of Oceanography. The organization was formed in 1949 to study the ecological aspects of the sardine population collapse off California. Today our focus has shifted to the study of the marine environment off the coast of California, the management of its living resources, and monitoring the indicators of El Nino and climate change. CalCOFI conducts quarterly cruises off southern and central California, collecting a suite of hydrographic and biological data on station and underway. Data collected at depths down to 500 meters include: temperature, salinity, oxygen, phosphate, silicate, nitrate and nitrite, chlorophyll, transmissometer, PAR, C14 primary productivity, phytoplankton biodiversity, zooplankton biomass, and zooplankton biodiversity.
