Codium
''Codium'' is a genus of seaweed in the Chlorophyta of the order Bryopsidales. Paul Silva was an expert on the genus ''Codium'' taxonomy at the University of California, Berkeley. There are about 50 species worldwide. Description The genus has thalli of two forms, either erect or prostrate. The erect plants are dichotomously branched to long with branches forming a compact spongy structure, not calcareous. The final branches form a surface layer of close palisade cortex of utricles. The non-erect species form either a prostrate or globular thallus with a velvet-like surface, the final branches forming a close cortex of utricles. Distribution Ireland Two of these species are very rare in Ireland. '' Codium adhaerens'' has been recorded from a few sites on the west coast and from Tory Island on the north coast in County Donegal. In 1837 it was found in Church Bay in County Antrim,Morton,O. 1994. ''Marine Algae of Northern Ireland.'' Ulster Museum. but has not been found the ...

Codium Spongiosum
''Codium spongiosum'' is a species of seaweed in the family Codiaceae. The light-green thallus has an applanate to pulvinate habit and is usually around across and thick. It has irregular lobes and moderately firm while alive becoming more spongy once dead. The utricles form in large clusters and are long and coated in many hairs. The species is similar to '' Codium lucasii'' which adheres more tightly to rock surfaces. It is epilithic in the subtidal to intertidal zones. Mostly situated in calmer waters from the low tide mark to several metres depth. It is often found in warmer waters but has a scattered distribution in colder waters. The species was first formally described by the botanist Harvey in 1855 in ''Some account of the marine botany of the colony of Western Australia,'' published in the ''Transactions of the Royal Irish Academy''. The type specimen was collected from King George Sound along the south coast of Western Australia. In Western Australia is found al ...

Seaweed
Seaweed, or macroalgae, refers to thousands of species of macroscopic, multicellular, marine algae. The term includes some types of '' Rhodophyta'' (red), ''Phaeophyta'' (brown) and ''Chlorophyta'' (green) macroalgae. Seaweed species such as kelps provide essential nursery habitat for fisheries and other marine species and thus protect food sources; other species, such as planktonic algae, play a vital role in capturing carbon, producing at least 50% of Earth's oxygen. Natural seaweed ecosystems are sometimes under threat from human activity. For example, mechanical dredging of kelp destroys the resource and dependent fisheries. Other forces also threaten some seaweed ecosystems; a wasting disease in predators of purple urchins has led to a urchin population surge which destroyed large kelp forest regions off the coast of California. Humans have a long history of cultivating seaweeds for their uses. In recent years, seaweed farming has become a global agricultural practic ...

Paul Silva
Paul Claude Silva (October 31, 1922 – June 12, 2014) was a phycologist, marine biologist, and algal taxonomist considered to be the world's leading expert in the chlorophyte green algal genus ''Codium''. Silva was also an expert in botanical nomenclature and was an editor of the International Code of Botanical Nomenclature's Eighth through Sixteenth International Botanical Congresses. Biography Silva completed his undergraduate degree at the University of Southern California, though his education was interrupted by World War II. He served in the US Navy on the USS Darby, participating in the Battle of Leyte Gulf. He attended Stanford University for his master's degree studying under Gilbert Morgan Smith, and University of California, Berkeley for his Ph.D. Silva later worked as a Research Botanist and Curator of Algae at the UCB herbarium.

Bryopsidales
Bryopsidales is an order of green algae, in the class Ulvophyceae. Characteristics The thallus is filamentous and much branched and may be packed into a mass. It is coenocytic, having multi-nucleate cells consisting of cytoplasm contained within a cylindrical cell wall. There are no septae and the many discoid chloroplasts, nuclei and other organelles are free to move through the organism. The whole organism may consist of a single cell and in the genus ''Caulerpa'' this may be several metres across. In the genus '' Halimeda'', whole seabed meadows may consist of an individual, single-celled organism connected by filamentous threads running through the substrate. Reproduction Propagation is normally vegetative from small fragments which grow into new individuals. Under certain conditions sexual reproduction occurs in a process called holocarpy. Almost all of the cytoplasm in the thallus is converted into biflagellate gametes, which are discharged into the sea through papillae ...

Belfast
Belfast ( , ; from ga, Béal Feirste , meaning 'mouth of the sand-bank ford') is the capital and largest city of Northern Ireland, standing on the banks of the River Lagan on the east coast. It is the 12th-largest city in the United Kingdom and the second-largest in Ireland. It had a population of 345,418 . By the early 19th century, Belfast was a major port. It played an important role in the Industrial Revolution in Ireland, briefly becoming the biggest linen-producer in the world, earning it the nickname "Linenopolis". By the time it was granted city status in 1888, it was a major centre of Irish linen production, tobacco-processing and rope-making. Shipbuilding was also a key industry; the Harland and Wolff shipyard, which built the , was the world's largest shipyard. Industrialisation, and the resulting inward migration, made Belfast one of Ireland's biggest cities. Following the partition of Ireland in 1921, Belfast became the seat of government for Northern Ireland ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mulroy Bay
Mulroy Bay ( ga, Cuan na Maoil Ruaidh) is a relatively small bay / sea loch on the north coast of County Donegal, Ireland. Mulroy Bay is the most convoluted of the marine inlets in north-west Ireland. It is approximately 12 km long in a north-south direction. The entrance to the bay is a narrow embayment leading to a winding entrance channel 10 km in length. This channel varies in width and depth, with three significant narrows only 100–150 m across, where the current reaches maxima of 3-5 knots. It opens into the Broad Water, an open shallow sea lough 8 km from north to south and 2.5 km from east to west, generally less than 20 m in depth and with many small rocky islands and islets. Settlements founded on the bay include Milford, Kerrykeel and Cranford. The English name of the bay comes from ''Cuan na Mhaoil Ruaidh'', the original Irish language name for the bay which means 'Bay of the Red Current' or 'Bay of the Red Stream'.Patrick M ...
