Plymouth researchers will be presenting new research findings at an international conference they are hosting in the city next month.

Professor Paul Worsfold, Co-director of Plymouth Environmental Research Centre (PERC), heads the Plymouth team working on a three-year research project which investigates the role of iron in ocean productivity and climate change. Plymouth is one of 12 European universities taking part in this ‘IRONAGES’ project.

Professor Worsfold commented: “We are

The SUMER instrument on the ESA-NASA SOHO spacecraft has measured amazing wind speeds during its observations of the Sun. It sets a new record in its examination of two loops of gas arching in the solar atmosphere, where NASA`s TRACE satellite spotted bright blobs of gas. Shifts in the wavelength of ultraviolet light from highly ionized neon atoms, seen by SUMER, revealed steady wind speeds of up to 320 000 kilometres per hour. That`s fast enough to cross the Atlantic Ocean in less than a minute.

Record low numbers of highly-prized squid have devastated the Falkland Islands fishery this year. Less than 10,000 tonnes have been caught so far, making this the worst year since the fishery began in 1987. As described in this week`s SCIENCE British Antarctic Survey (BAS) scientists believe unfavourable oceanographic conditions in squid spawning grounds caused the slump in the fishery which is normally worth £17 million ($US 25 million) in licence fees.

The flying squid Illex argentinu

Core samples taken from far below the ocean floor are helping a University of Edinburgh geologist to form a picture of dramatic climate changes which took place 30 to 40 million years ago. Dr Bridget Wade is part of an international team of scientists studying climate shifts between the Eocene period – the warmest cycle in the last 65 million years – and the cooler Oligocene period, which saw the first major build-up of Antarctic ice. The study could shed new light on present climate trends as the Eo

Animals may have beaten upright plants to land.

The oldest fossils of footprints ever found on land hint that animals may have beaten plants out of the primordial seas. Lobster-sized, centipede-like animals made the prints wading out of the ocean and scuttling over sand dunes about 530 million years ago. Previous fossils indicated that animals didn’t take this step until 40 million years later.

“It’s staggering that we thought for all this time that animals appeared on land

Discarded human debris is encouraging colonization of exotic marine animals in the world`s oceans and threatening global biodiversity, particularly in the Southern Ocean. The findings, reported in this week`s NATURE, are based on a 10-year study of human litter (mostly plastic) washed ashore on 30 remote islands around the globe, from the Arctic to the Antarctic.

David Barnes of the British Antarctic Survey (BAS) found that man-made rubbish in the seas, especially plastics, has almost double
