In the northern North Sea, the water column stratifies in summer as the surface layer warms. At the base of this surface layer, intense algal blooms can develop. Since these cannot be seen from space, these layers have been much less well studied than blooms in surface layers. However, preliminary data suggests these regions may be very important in sustaining overall plankton growth in the North Sea, particularly in summer and this plankton production may also be important in sustaining fish growth. This proposal seeks support to study these layers and use the information gained to assess their significance for overall productivity. Climate change is likely to increase stratification in the North Sea and we will also assess the impacts of such changes on phytoplankton productivity and fisheries.

在北海北部，夏季，随着表层变暖，水柱分层。在这个表层的底部，会出现大量的藻华。由于从太空中无法看到这些层，因此对这些层的研究比表面层的水华要少得多。然而，初步数据表明，这些区域对于维持北海浮游生物的整体生长可能非常重要，特别是在夏季，而且浮游生物的生产对于维持鱼类生长也可能很重要。该提案寻求支持来研究这些层并使用获得的信息来评估它们对整体生产力的重要性。气候变化可能会加剧北海的分层，我们还将评估此类变化对浮游植物生产力和渔业的影响。
