The Chicago Park District maintains sensors in the water at beaches along Chicago's Lake Michigan lakefront. These sensors generally capture the indicated measurements hourly while the sensors are in operation during the summer. During other seasons and at some other times, information from the sensors may not be available. See https://data.cityofchicago.org/d/k7hf-8y75 for a dataset with land-based weather measurements at selected beaches. The sensor locations are listed at https://data.cityofchicago.org/d/g3ip-u8rb.

Please note that sensor locations change with the Park District’s operational needs, primarily related to water quality. For more information on beach operations, please see https://www.chicagoparkdistrict.com/parks-facilities/beaches.

This dataset contains the results of replicate experiments which measured the total hydrocarbon content (THC) in water accommodated fractions (WAFs) of three fuels; Special Antarctic Blend diesel, Marine Gas oil and intermediate fuel oil IFO 180.

This dataset contains the underway data collected during the Aurora Australis Voyage V1 2007/08 (SIPEX). This voyage began in Hobart, and travelled to the ice edge where a large number of scientific observations were collected. Underway (meteorological) data are available online via the Australian Antarctic Division Data Centre web page (or via the Related URL section).

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Sea ice in Canada indicators provide information on the area of sea in Canada covered by ice during the summer season. Sea ice area represents the portion of marine area covered by ice. The area is evaluated using the Canadian Ice Service Digital Archive and is expressed in thousands or millions of square kilometres. The Sea ice in Canada indicators are provided for the Northern Canadian Waters, by sub-region and for the Northwest Passage. The indicators also present trends in total sea ice area and multi-year sea ice area. Multi-year sea ice is defined as sea ice that has survived at least one summer's melt. Sea ice is an indicator of how the climate is changing. It is a critical component of our planet because it influences the Arctic and global climate, ecosystems, and people who live in the polar regions. Sea ice influences the climate through the sea ice–albedo feedback effect (or reflectivity of the Earth's surface). Changes in sea ice can also affect ocean currents and the exchange of heat and water vapour from the ocean to the atmosphere. Sea ice affects marine transportation, commercial fishing, offshore resource development, the hunting and fishing patterns of Indigenous peoples, and tourism and recreation. Understanding how Canada's climate is changing is important for developing adaptive responses. The Sea ice in Canada indicators provide a way to communicate to Canadians how the coverage of Canada's Arctic sea ice has changed. The Intergovernmental Panel on Climate Change and the World Meteorological Organization use sea ice, among several other variables, to assess long-term changes in climate. Sea ice is considered by the World Meteorological Organization's Global Climate Observing System to be an Essential Climate Variable. Information is provided to Canadians in a number of formats including: static and interactive maps, charts and graphs, HTML and CSV data tables and downloadable reports. See the supplementary documentation for the data sources and details on how the data were collected and how the indicator was calculated.

Raw GPS and ship motion data collected during the Antarctic Circumnavigation Expedition 2016/2017.

Waves in the Southern Ocean are the biggest on the planet. They exert extreme stresses on the coastline of the Sub-Antarctic Islands, which affects coastal morphology and the delicate natural environment that the coastline offers. In Antarctic waters, the sea ice cover reflects a large proportion of the wave energy, creating a complicated sea state close to the ice edge. The remaining proportion of the wave energy penetrates deep into the ice-covered ocean and breaks the ice into relatively small floes. Then, the waves herd the floes and cause them to collide and raft.

There is a lack of field data in the Sub-Antarctic and Antarctic Oceans. Thus, wave models are not well calibrated and perform poorly in these regions. Uncertainties relate to the difficulties to model the strong interactions between waves and currents (the Antarctic Circumpolar and tidal currents) and between waves and ice (reflected waves modify the incident field and ice floes affect transmission into the ice-covered ocean). Drawbacks in wave modelling undermine our understanding and ability to protect this delicate ocean and coastal environment.

By installing a Wave and Surface Current Monitoring System (WaMoS II, a marine X-Band radar) on the research vessel Akademic Thresnikov and using the meteo-station and GPS on-board, this project has produced a large database of winds, waves and surface currents. Dara were collected during the Antarctic Circmumnavigaion Expedition, which took place from Dec. 2016 to Mar. 2017. The instrumentation operated in any weather and visibility conditions, and at night, monitoring the ocean continuously over the entire Circumnavigation.

Records can support

1. the assessment of metocean conditions in the Southern Oceans; and

2. calibration and validation of wave and global circulation models.

Data - AAS_4434_ACE_GPS contains basic metereological conditions acquired form the ship’s meteo-station, gepgraphical coordinates (latitude, longitude and altitude) from the ship’s GPS and ship motion data from the ship’s Inertial Measurement Unit (IMU). These data are stored as time series with a sampling frequency of 1Hz.

Abstract: Hardshell marine turtles - most commonly greens and loggerheads are occasionally found alive or dead on South Australian beaches.
Often they are not in good condition, and require rehabilitation.
Paddy is an exception, and is fat and healthy.
We will find out in June from her DNA test, where she hatched about 35 years ago, and in the meantime her travels will tell us whether she is a local SA resident, or passing through - possibly after nesting last summer.
She was found at Middleton Beach 16th March 2023 in a large amount of seaweed, which may have restricted and exhausted her.
She arrived at Adelaide Zoo on St Patricks Day 17th March 2023 - hence the name Paddy.
She spent the next 2 weeks being examined and cared for by the Vets and Nurses at Adelaide Zoo.
After discussion with Marine Science turtle experts in Western Australia and Queensland - the decision was made by Marine Parks SA to release her on 31st March close to where she was found - Rapid Bay was chosen - away from the weed that may have slowed her swimming.
Her satellite tracker was borrowed at very short notice from the Marine Science section of the WA Parks and Wildlife, and has shown her head North up Gulf St Vincent, where she reached the head on 13th April.
She basked on mudflats near Port Wakefield on 14th April, and for a second time on an isolated beach 27km north of Port Adelaide's Outer Harbour on 22nd April, after gradually swimming back down from the top of Gulf St Vincent.
She spent more than a week from the 24th April in the Port Adelaide estuary, and soon after 1st May swam across the Gulf to be 5km off the coast of the Yorke Peninsula on 5th May and began heading south until 10th May 2023, when she rounded the heel of the Peninsula at Troubridge Shoal Lighthouse, and began swimming west.
She followed the southern coast of Yorke Peninsula at about 17km a day, then swam NW crossing 140km of Spencer Gulf in 3 days to get to the coast of Eyre Peninsula on 19th May 2023.
A signal on 23rd May gave a temperature of 15.2C, but no location. The cooler temperature suggested that she may have still been in Spencer Gulf, as the offshore waters are currently up to 4C degrees higher - and this proved to be correct when she gave a good ARGOS Class 1 location inside Franklin Harbour Marine Park 7 days later on 26th May 2023, 70km to the north. This bay is rich in seagrass, and she has plenty to forage on here.
