There is no sharp distinction between seas and oceans, though generally seas are smaller, and are often partly (as marginal seas or particularly as a mediterranean sea) or wholly (as inland seas) enclosed by land. White light is made up of many different visible colours ranging from red to violet – red has the longest wavelength, blue light the shortest. Here it is gradually warmed, becomes less dense, rises towards the surface and loops back on itself. This person has just told me to drown – I believe that is a threat to kill,” wrote the MP for Bristol West on Twitter after receiving the message on 15 July.

It can also enter through rivers as dissolved organic carbon and is converted by photosynthetic organisms into organic carbon. Sarah Jones and Jenny Salmon from our Engagement Team attended the annual Towards Zero Suicide conference.Take your shoes off: “Get out there, just a glimpse of the sea or getting a few grains of sand on your toes can change your entire outlook for the day,” says Joe T. Most waves are less than 3 m (10 ft) high [47] and it is not unusual for strong storms to double or triple that height; [48] offshore construction such as wind farms and oil platforms use metocean statistics from measurements in computing the wave forces (due to for instance the hundred-year wave) they are designed against. These gyres have followed the same routes for millennia, guided by the topography of the land, the wind direction and the Coriolis effect. The relatively thin lithosphere floats on the weaker and hotter mantle below and is fractured into a number of tectonic plates. This can either be exchanged throughout the food chain or precipitated into the deeper, more carbon-rich layers as dead soft tissue or in shells and bones as calcium carbonate.

Phytoplankton are really important as they produce more than 50% of the world's oxygen (meaning every second breath you take comes from the sea! Being by the sea also forces us to change our pace of living which can alter how we think and process information.Close to the seabed live demersal fish that feed largely on pelagic organisms or benthic invertebrates.

In an interview with The Guardian, Dr Mathew White, an environmental psychologist, said there are three key factors which link coastal living and wellbeing.

m) per second, can form at different places at different stages of the tide and can carry away unwary bathers. In 1759, John Harrison, a clockmaker, designed such an instrument and James Cook used it in his voyages of exploration.

From 1st October 2023 to 18th January 2024, there have been 216 confirmed cases across the West Midlands. Scientific oceanography began with the voyages of Captain James Cook from 1768 to 1779, describing the Pacific with unprecedented precision from 71 degrees South to 71 degrees North. The high salt content increases the water's density, which is why people float in the Dead Sea more easily than in the ocean.We can slow down, stepping away from the frenetic digital world and allowing us to simply take time to be fully present in the moment.
