River Tees

Teesmouth Lifeboat Station was a Royal National Lifeboat Institution (RNLI) lifeboat station, situated on the mouth of the River Tees, South Gare, North Yorkshire, England. The lifeboat station had been operating at Teesmouth for 177 years when it was closed by the RNLI in 2006. The withdrawal of the lifeboat capability from Teesmouth was subject to much criticism from the local council and the volunteers who crewed the boat, but the RNLI stated that there was an over-provision of lifeboat cover on the north-east coast. The former lifeboat house was demolished in 2010, four years after the station had closed.

South Gare is an area of reclaimed land and breakwater on the southern side of the mouth of the River Tees in Redcar and Cleveland, England. It is accessed by taking the South Gare Road (private road) from Fisherman's Crossing at the western end of Tod Point Road in Warrenby. Before the building of South Gare, permanent dry land stopped at Tod Point, at the western end of Warrenby, and there was only Coatham Sands and the mudflats of Bran Sands. The creation of South Gare extends this by a further 2.5 miles (4.0 km). The building of South Gare offers a safe harbour in stormy weather to ships off the coast and allowed for the dredging of the River Tees entrance. South Gare itself was a settlement but the houses there were demolished many years ago.

The 2021 North-East England shellfish die-off was a series of occasions where a mass of shellfish were found on beaches on the Durham and Yorkshire Coasts in northern England, either dead, or in stages of dying. These events first occurred in October 2021, with re-occurrences in February, and September 2022, with concerns being raised at the amount of crabs, lobsters and other marine animals found dead. An initial investigation by the Department for Environment, Food and Rural Affairs (Defra) stated a large algal bloom had killed off the marine life. However, those working in the fishing industry and independent scientists, claimed the deaths was caused by pyridine poisoning, an effect of dredging in the River Tees. A second government investigation, published in January 2023, stated neither an algal bloom or pyridine poisoning could explain the deaths over such a long period of time, wide area and the unusual twitching in crabs. The scientists concluded that a disease, "novel pathogen" was the "most likely cause of the mortality."

Seaton Dunes and Common (grid reference NZ535285) is a 312.1 hectare biological Site of Special Scientific Interest in Hartlepool, County Durham, England notified in 1966. Part of it is a Local Nature Reserve.SSSIs are designated by Natural England, formally English Nature, which uses the 1974–1996 county system. This means there is no grouping of SSSIs by Hartlepool unitary authority, or County Durham which is the relevant ceremonial county . As such Seaton Dunes and Common is one of 18 SSSIs in the Cleveland area of search.

Redcar Bulk Terminal (RBT), also known as Redcar Ore Terminal, is a privately run dock at the mouth of the Tees Estuary in North Yorkshire, England. The port is used for the transhipment of coal and coke (both inward and outward flows) and for many years was the import dock for iron ore destined for Redcar Steelworks under British Steel Corporation, British Steel plc, Corus, Tata Steel Europe and Sahaviriya Steel Industries (SSI UK). The port is not part of the Teesport estate run by PD Ports but is instead owned by SSI UK (in liquidation). It is one of only four UK ports that are capable of handling Capesize vessels.

The Seaton Carew Wreck is a protected wrecksite lying in the intertidal zone at Seaton Carew. Prior to 1996 the wreck had been completely covered by the sand of the beach, but it was exposed in 1996 and 2002 and has been regularly exposed since 2004. The wreck is of a type of vessel known as a collier brig which would have been ubiquitous in the 18th and 19th centuries and is unusual on the North-East coast for the high degree of preservation. The wreck is a Protected Wreck managed by Historic England.

Hartlepool nuclear power station is a nuclear power station situated on the northern bank of the mouth of the River Tees, 2.5 mi (4 kilometres) south of Hartlepool in County Durham, North East England. The station has a net electrical output of 1,185 megawatts, which is 2% of Great Britain's peak electricity demand of 60 GW. Electricity is produced through the use of two advanced gas-cooled reactors (AGR). Hartlepool was only the third nuclear power station in the United Kingdom to use AGR technology. It was also the first nuclear power station to be built close to a major urban area. Originally planned in 1967, with construction starting in 1969, the station started generating electricity in 1983, and was completed in 1985, initially being operated by the Central Electricity Generating Board. With privatisation of the UK's electric supply industry in 1990, the station has been owned by Nuclear Electric and British Energy, but is now owned and operated by EDF Energy. On 18 October 2010 the British government announced that Hartlepool was one of the eight sites it considered suitable for future nuclear power stations.The power station will cease power generation in March 2026, prior to defueling and decommissioning.

Seal Sands (grid reference NZ529260) is a 294.37 hectare biological Site of Special Scientific Interest in County Durham, England, notified in 1966. Situated in the mouth of the River Tees next to Greatham Creek and Seaton-on-Tees Channel, the site is accessible from the A178 road running between Seaton Carew and Port Clarence. SSSIs are designated by Natural England, formerly English Nature, which uses the 1974–1996 county system. This means there is no grouping of SSSIs by Stockton-on-Tees unitary authority, or County Durham which is the relevant ceremonial county. As such Seal Sands is one of 18 SSSIs in the Cleveland area of search.An area of reclaimed land is given over to chemical industries.

Tees Bay is a bay in County Durham, England, between Hartlepool and Redcar, where the River Tees flows into the North Sea.

Seaton Carew is a seaside resort in the Borough of Hartlepool in County Durham, England. It had an estimated population of 6,018. The area is named after a Norman French family called Carou who owned lands in the area and settled there, while 'Seaton' means farmstead or settlement by the sea.It separated from Hartlepool by the Durham Coast Line and some greenbelt land along the shore. The resort is on the North Sea coast and north of the River Tees estuary.

Teesport is a large sea port located in the unitary authority of Redcar and Cleveland, in the ceremonial county of North Yorkshire, Northern England. Owned by PD Ports, it is located approximately 1 mile (2 km) inland from the North Sea and 4 miles (6 km) east of Middlesbrough on the River Tees. Teesport is currently the third largest port in the United Kingdom, and amongst the ten biggest in Western Europe, handling over 56 million tonnes of domestic and international cargo per year.

Warrenby Halt was a railway station opened in 1920 having been built to serve the village of Warrenby in Redcar and Cleveland, England and the nearby Dorman Long works. It consisted of wooden platforms and brick-built shelters and was gas-lit.In 1978 the railway was diverted to allow for the building of the Redcar steelworks, leaving Warrenby bypassed. A new station, Redcar British Steel, opened on the deviation line to take its place. (The replacement station was officially the quietest station on the entire British rail network with only 40 passengers in 2017–18.) One of Warrenby Halt's platforms survives at Newton Dale Halt on the North Yorkshire Moors Railway.
