Reef-Platform Coral Boulders: Evidence for High-Energy Marine Inundation Events on Tropical Coastlines

The first aim here's to provide a treatise at the value and cost of coarse clastic carbonate sediments (i. e. huge coral boulders) on tropical coastlines for figuring out either glossy and pre-historical (Holocene) high-magnitude marine inundation occasions. there was a fast groundswell of curiosity in huge carbonate blocks on tropical coasts over the past decade, but it isn't greatly favored that such positive aspects have been saw and recorded again within the early explorations of Matthew Flinders at the nice Barrier Reef within the 1800s.

Design of Coastal Structures and Sea Defenses

Coastal constructions are a tremendous part in any coastal safeguard scheme. They at once regulate wave and hurricane surge motion or to stabilize a seashore which gives defense to the coast. This publication offers the main up to date technical advances at the layout and development of coastal buildings and sea defenses.

Ray and Wave Chaos in Ocean Acoustics - Chaos in Waveguides

A scientific learn of chaotic ray dynamics in underwater acoustic waveguides all started within the mid-1990s whilst it was once discovered that this issue performs a vital function in long-range sound propagation within the ocean. The phenomenon of ray chaos and its manifestation at a finite wavelength -- wave chaos -- were investigated by way of combining equipment from the speculation of wave propagation and the idea of dynamical and quantum chaos.

Oceanography: An Invitation to Marine Science

2003: Portland, Dorset. 2008: Blyth, Northumberland. 56 Vulnerable Hooded Seal Cystophora cristata Adult length: 2·0–2·6 m Adult weight: 145–400 kg IDENTIFICATION: The species owes its name to the fleshy, wide muzzle that droops down over the mouth of adult males. When inflated, this nasal cavity forms a conspicuous ‘hood’ on the top of the head, significantly altering the profile of the animal. This effect can be further enhanced by the inflation of a large, pinkish-red membrane from within the left nostril.

Some animals may have a reddish, rusty hue to their coats. The underparts may be somewhat lighter than the upperparts, though the fur can be uniformly coloured. Overlaying this base colour is a conspicuous pattern of spots, rings and blotches, normally uniformly distributed on both the upper and underparts. SIMILAR SPECIES: The two species most likely to be encountered in British waters are Common Seal and Grey Seal (see page 52 for how to tell them apart). Other pinniped species are encountered only very rarely in Britain (pages 53–57), but are distinctive.

The head-shape and conformation is identical, and diagnostic, especially in comparison with female Grey Seals.
