Phytoplankton are free-floating plants found in marine and freshwaters that, through their photosynthetic growth, form the base of the aquatic food chain. A small subset of the phytoplankton may be harmful to human health or to human use of the ecosystem. The species that cause harm are now widely referred to as 'Harmful Algae' with the term 'Harmful Algal Bloom' (HAB) commonly being used to describe their occurrence and effects.Some HABs can be harmful to humans through their production of biotoxins that are concentrated in the flesh of filter feeding shellfish, leading to a health risk if the shellfish are consumed by humans. Other HABs can kill farmed fish. HAB events of either type can have serious financial consequences for aquaculture.Early warning of HAB events provides a mechanism to protect human health and minimise business risk for aquaculture.Many important HABs develop offshore. Two of the most important in the UK and worldwide are the genus Dinophysis sp. that causes diarrhetic shellfish poisoning, and the species Karenia mikimotoi that can kill farmed fish. These organisms are transported to coastal aquaculture sites by oceanic currents. For K. mikimotoi we can use satellite remote sensing to identify their offshore blooms, for Dinophysis we know the locations and times of the year that are most high risk.In this project we shall use a combination of satellite remote sensing, in situ measurement (using free floating and moored scientific instruments that measure the properties of the water column) and mathematical modelling of oceanic currents and HABs to get a better understanding of where these harmful blooms develop and under what conditions they will be transported to the coast and subsequently into the fjords where aqaculture is located. Our results will be used to improve risk assessment bulletins that are produced weekly for use by aquaculture practitioners. The new knowledge gained in this project will allow us, for the first time, to interpret modelled ocean current forecasts to provide forecasts of the likelihood of these currents carrying advective HABs to the coast. The work will also allow us to determine if on reaching the coast, water exchange will allow blooms to enter the sheltered fjords within which aquaculture is practiced. This will allow industry to better plan their husbandry and harvesting to minimise HAB risk to business and health.

浮游植物是在海洋和淡水中发现的自由漂浮的植物，通过它们的光合作用生长，形成水生食物链的基础。浮游植物的一小部分可能对人类健康或人类对生态系统的使用有害。造成危害的物种现在被广泛称为"有害藻类"，"有害藻华"一词通常用来描述它们的发生和影响。一些有害藻华会产生生物毒素，集中在滤食性贝类的肉中，对人类有害，如果人类食用贝类，会对健康造成威胁。其他有害生物会杀死养殖鱼类。任何一种类型的赤潮事件都可能对水产养殖造成严重的经济后果。赤潮事件的早期预警提供了一种保护人类健康和最大限度地减少水产养殖商业风险的机制。许多重要的赤潮都在近海发展。在英国和世界范围内最重要的两种是导致贝类中毒的甲藻属，以及可以杀死养殖鱼类的Karenia mikimotoi。这些生物通过洋流被运送到沿海水产养殖场。克雷mikimotoi，我们可以使用卫星遥感来识别他们的近海水华，对于甲藻，我们知道一年中最高风险的位置和时间。在这个项目中，我们将使用卫星遥感的组合，原位测量（使用自由漂浮和系泊的科学仪器测量水柱的特性）以及洋流和有害藻华的数学模型，以便更好地了解这些有害藻华在何处形成，以及在何种条件下它们将被转移到海岸，随后进入海湾所在的峡湾。我们的研究结果将用于改进每周制作的供水产养殖从业人员使用的风险评估公告。在这个项目中获得的新知识将使我们能够第一次解释模拟洋流预测，以预测这些洋流携带平流有害生物到海岸的可能性。这项工作还将使我们能够确定在到达海岸后，水交换是否会允许水华进入进行水产养殖的避风峡湾。这将使行业能够更好地规划其饲养和收获，以尽量减少有害藻华对商业和健康的风险。
