Cossack, Western Australia
Cossack is an historic ghost town located 1,480 km north of Perth and 15 km from Roebourne in the Pilbara region of Western Australia. The nearest town to Cossack is Wickham. Cossack is located on Butchers Inlet at the mouth of the Harding River. It is reached by a single, sealed road that follows the original causeway across a series of tidal salt flats. The overall landform of the region around Cossack is a low, flat plain with occasional rocky hills and ranges. The vegetation is mainly grass, spinifex and low shrub, with occasional trees (mangroves) along watercourses and in gullies. The mangrove scrub becomes quite dense along the shoreline and at the mouth of the inlet. The main road from Roebourne to Cossack continues past the town of Wickham and the Cape Lambert iron ore port (operated by Pilbara Iron), and terminates at the fishing town of Point Samson. The townsite is not visible from the main road, and only becomes apparent as the road rounds Nanny Goat Hill. The site of the former town is defined by Nanny Goat Hill, Tien Tsin Lookout, the hilly ground to the north-east and north-west, and Butchers Inlet to the east and south-east. Past the townsite, the road winds up to the Reader Head Lookout, from which sweeping views of the surrounding coastline can be seen. Many of the buildings are listed by the National Trust. The erstwhile Tien Tsin Harbour is now known as Port Walcott

McClure Arctic Expedition
The McClure Arctic Expedition of 1850, among numerous British search efforts to determine the fate of the Franklin's lost expedition, is distinguished as the voyage during which Robert McClure became the first person to confirm and transit the Northwest Passage by a combination of sea travel and sledging. McClure and his crew spent three years locked in the pack ice aboard HMS Investigator before abandoning it and making their escape across the ice. Rescued by HMS Resolute, which was itself later lost to the ice, McClure returned to England in 1854, where he was knighted and rewarded for completing the passage.

Juncal Formation
The Juncal Formation (also Juncal Shale) (/ˈdʒʊŋkɑːl, ˈhuːŋ/) is a prominent sedimentary geologic unit of Eocene age found in and north of the Santa Ynez Mountain range in southern and central Santa Barbara County and central Ventura County, California. An enormously thick series of sediments deposited over millions of years in environments ranging from nearshore to deep water, it makes up much of the crest of the Santa Ynez range north of Montecito, as well as portions of the San Rafael Mountains in the interior of the county. Its softer shales weather to saddles and swales, supporting a dense growth of brush, and its sandstones form prominent outcrops.

Ecological Effects of Biodiversity
The diversity of species and genes in ecological communities affects the functioning of these communities. These ecological effects of biodiversity in turn are affected by both climate change through enhanced greenhouse gases, aerosols and loss of land cover, and biological diversity, causing a rapid loss of biodiversity and extinctions of species and local populations. The current rate of extinction is sometimes considered a mass extinction, with current species extinction rates on the order of 100 to 1000 times as high as in the past. The two main areas where the effect of biodiversity on ecosystem function have been studied are the relationship between diversity and productivity, and the relationship between diversity and community stability. More biologically diverse communities appear to be more productive (in terms of biomass production) than are less diverse communities, and they appear to be more stable in the face of perturbations. Also animals that inhabit an area may alter the surviving conditions by factors assimilated by climate.

1968 Burma Cyclone
The 1968 Burma cyclone was regarded as the worst to strike the country during the 20th century before it was surpassed by another unnamed cyclone in 2004 and further, Cyclone Nargis in 2008, respectively. The first tropical cyclone of the 1968 North Indian Ocean cyclone season, it started as a depression on May 7 on the northern Andaman Sea. With low wind shear and warm sea surface temperatures, the storm intensified in the waters near Burma before heading northwestwards. It then started to rapidly intensify, with an eye becoming apparent on satellite imagery on May 9. Also that day, it reached its peak intensity, with 3-minute maximum sustained winds of 220 km/h (140 mph) by the Indian Meteorological Department, which is equivalent to a super cyclonic storm; however, the agency treated the system as a severe cyclonic storm. Little to no changes happened on the cyclone as it turned northeastwards, making landfall near Akyab (now Sittwe) between 18:00 and 21:00 UTC on that day. Land interaction rapidly weakened the storm, dissipating on May 10 as an area of low-pressure in south Chin State. The predecessor to the cyclone caused light to moderate downpour to the Andaman Islands; however, no deaths were reported. Winds reported from the cyclone inland Burma reached an estimate of 60–100 mph, altogether with heavy rainfall and large storm surges. The former flooded the crops, submerging them in floodwaters in the process while the latter washed out villages near the path of the storm. Schools and hospitals throughout Akyab were destroyed by high winds and large waves, while the port suffered major damages. The town was almost destroyed due to the storm. In addition, some ships in the said harbor, including the Greek freighter Geros Michalos were reportedly sunk in the Bay of Bengal. Houses were destroyed during the storm and many livestock died, mainly due to drowning. The death toll from the cyclone was finalized on May 1968 at 1,307 individuals, while 2,000 more were reportedly missing. The property damages were estimated at K15 million kyat ($3.248 million United States dollar ). After the cyclone, the Government of Burma started to release aid to the victims, altogether with food supplies and cotton blankets. The Red Cross Society of the country donated cases of medicines to the country, while the United States Government released over 25,000 blankets to be transferred to the area. In addition, many countries and organizations including the UNICEF contributed over $121,291 (1968 USD) to Myanmar, following the disaster.

Oregon Badlands Wilderness
The Oregon Badlands Wilderness is a 29,301-acre (11,858 ha) wilderness area located east of Bend in Deschutes and Crook counties in the U.S. state of Oregon. The wilderness is managed by the Bureau of Land Management as part of the National Landscape Conservation System and was created by the Omnibus Public Land Management Act of 2009, which was signed into law by President Barack Obama on 30 March 2009. The area is known for igneous castle-like rock formations, harsh terrain, ancient Juniper trees, sagebrush, and extensive arid land. Desert wildflowers, dry river canyons, and Native American pictographs can be found. The blind iditarod racer Rachel Scdoris trained in the area, and the wilderness is home to the western terminus of the Oregon Desert Trail.

Enhanced 9-1-1
Enhanced 911, E-911 or E911 is a system used in North America to automatically provide the caller's location to 911 dispatchers. 911 is the universal emergency telephone number in the region. In the European Union, a similar system exists known as E112 (where 112 is the emergency access number) and known as eCall when called by a vehicle. An incoming 911 call is routed to a Public Safety Answering Point (PSAP), which is a call center operated by the local government. At the PSAP, the call is answered by a specially trained official known as a 9-1-1 dispatcher. The dispatcher's computer receives information from the telephone company about the physical address (for landlines) or geographic coordinates (for wireless) of the caller. This information is used to dispatch police, fire, medical, and other services as needed.

OpenMI Standard
The OpenMI (Open Modeling Interface) Standard defines an interface that allows models to exchange data in memory at run-time. When the standard is implemented, existing models can be run simultaneously and share information, for instance at each time step, making model integration feasible at the operational level. The OpenMI standard was created with the intent to facilitate model integration, which is helpful in understanding and predicting process interactions and achieving an integrated approach to environmental management. The OpenMI standard is owned and maintained by the OpenMI Association, an open, not for profit group of international organizations and people. On the 1st of July 2014 the Open Geospatial Consortium (OGC®) membership has approved the Open Modelling Interface Standard Version 2 (OpenMI) as an OGC standard.
