| It is almost impossible to fish the Lancaster Canal between The Bridges due to a surface algal bloom and weed. |
|
| I descend through the green globs of the algal bloom, then into bottom visibility clouded by fine silt lifted by the tide. |
|
| There was an algal bloom in the summer, but toxins that could be produced by such a bloom have not been found in the lake, Dr. French says. |
|
| Blue-green algal bloom forms on the surface of water when there are high levels of nutrients present, combined with warm, sunny and calm conditions. |
|
| This algal bloom forms an unpleasant foam which creates a nuisance for tourists, but is not believed to have a toxic effect. |
|
| Too much biological productivity, such as when a lake experiences an algal bloom, means that one species ends up dominating the others. |
|
| Or you can pump water into the cages to dilute the algal concentration and harvest the marketable fish before the algal bloom can get to them. |
|
| Profitability is also affected by increasingly frequent toxic algal bloom, or by specific local ecological problems. |
|
| By adding iron to the ocean, the researchers induced a massive algal bloom. |
|
| Scientists studying red tides previously believed that after an algal bloom, high concentrations of brevetoxins didn't last long in the marine environment. |
|
| Around the time the coral died, the skeletons showed changes in concentration of carbon isotopes, indicating a large algal bloom. |
|
| The evidence suggests that costs can be significant in a local context, especially in the event of an algal bloom in a popular recreational area or where there is shell-fishing farming. |
|
| Eutrophication can lead to rapid increases in the density of certain types of these phytoplankton, a phenomenon known as an algal bloom. |
|
| The water appears green in this image, indicating an algal bloom. |
|
| Scientists attribute the unusually potent and widespread algal bloom to unseasonably warm water temperatures as a result of the El Niño weather phenomenon. |
|
| The workshop will also examine the Phaeocystis algal bloom which affected the coastlines of Northern France, Belgium, Netherlands and the Southern coast of England earlier this year. |
|
| The focus of SAFARI is to use instruments on American and European satellites to collect information on phytoplankton fields and particularly the annual biological spring algal bloom. |
|
| The investment represents the company's contribution to a multi group approach to minimising the risk of a repeat of the 2009 outbreak of blue algal bloom at Llyn Padarn. |
|
| However, it's important for coastal managers and public health officials to know that the presence of an algal bloom doesn't necessarily mean toxins are present. |
|
| Fast forward to the fall of 2015 and anglers were again facing major seagrass dieoffs triggered by high salinity, and a growing algal bloom is likely. |
|
|
|
| Red tide is a common name for a phenomenon known as an algal bloom when it is caused by a few species of dinoflagellates and the bloom takes on a red or brown color. |
