UPDATE WITH PICS 10.50am Thursday 24 June 2010

Swell is still 1 and a half foot now at low tide so there's a good chance it will be bigger and better as the rising tide starts pushing. Breeze is light 2-3 northwesterly onshore.

Tide times in earlier post below.

Here's a photo of last night's 3 foot sets. 23 June was Saint John's Eve, Bonfire Night with bonfires lighting up after sunset. Environmental concern seems to have trumped tradition last night with just 1 big toxic smoke cloud on Saint John's Point and a very small fire on Rossnowlagh Beach.

This morning the swell is 1 and a half to 2 foot with force 2 westerly onshore breeze. My camera has been misplaced. Photos as soon as I find it.

Below is the Marine Institute's report on the algal bloom that we've seen round the coast in recent weeks. The good news is that it's friendly. Thanks to Irish Surf Association for drawing Rossnowllagh Surf Report's attention to this:

Giant Bloom of Harmless Plankton Visible from Space

Both the European Space Agency (ESA) and NASA in the USA have recently released dramatic photographs of a giant “bloom” of harmless microscopic plants, known to marine scientists as ‘phytoplankton’, off the West Coast of Ireland.

 “Blooms of phytoplankton are important events in the sea and occur mainly during the summer months,” said Marine Institute scientist Joe Silke. “Phytoplankton are freely drifting, microscopic plants that convert sunlight and chemicals into plant material, just as plants do on land. They form the base of the marine food chain and are important contributors of atmospheric oxygen and essential components of a healthy oceanic biodiversity.” 

In recent weeks and in response to the fine weather, there have been reports of several blooms around the Irish coasts. The most dramatic of these - shown in the ESA photo of an algal bloom to the west of Ireland – was taken on the 23 May. The large swirls of turquoise water, south of the large cloud mass, are due to the presence of a species of phytoplankton known as Emiliania huxleyi.  

These phytoplankton are members of a group called the ‘coccolithophorids’ and are covered with an ‘armour plating’ of chalk plates. Each microscopic cell measure approximately four one thousandths of a millimetre in diameter and is therefore invisible to the naked eye. However, in response to warm surface waters and sunlight these tiny plants form blooms where billions of these cells can accumulate and cause the sea to turn a  milky white colour.

“This is clearly visible in the satellite images,” says Joe Silke. “The colour due to tiny calcium carbonate platelets that cover the cell and act as tiny mirrors reflecting light that strikes them, resulting in chalky white water. This resemblance to chalk is not incidental as the same coccoliths form chalk deposits including the famous White Cliffs of Dover and many other calcium carbonate coastal formations".  

Coccolithophores including Emiliania huxleyi could be susceptible to ocean acidification over the next 50 or so years as carbon dioxide diffuses across the sea-surface making the surface ocean more acidic, resulting in a detrimental impact on the occurrence of this beautiful natural phenomenon.  
“The presence of this bloom is a good sign that the waters to the west of Ireland are currently in a healthy state," says Silke. "Blooms such as these are important producers at the bottom of the food  chain and generate oxygen both in the sea and the atmosphere."
The Marine Institute National Phytoplankton Monitoring Programme is carried out year round to monitor the presence and impact of harmful species but also to identify occurrences of widespread  blooms of  public interest and to study trends in water quality.

Algal bloom

Satellite photo showing algae bloom around the coast of Ireland. Donegal isn't the worst but it explains some of the strange water colours we've been seeing and the muddy residue that the tide has dumped at both ends of the beach.

The calm seas for months past and recent warm weather are contributory factors. At least we don't have an uncapped BP oil well gushing anywhere close by.

Below this morning's pre-sunrise sky. Worth getting up early for (or going to bed late for. The cars the beach belong to a couple of savvy campers who have taken advantage of neap tides to pitch their tents above the tideline.)
