LION observatory data

the lion mooring is located in the center of the gulf of lion where one of the largest open sea convection happens in the winter period. this open sea convection is an active vertical mixing that concerns the whole northern mediterranean and can reach great deep in the gulf of lion (where it may even reach the bottom ~ 2500m) due to the mistral and tramontane, cold and dry winds. this is the phenomenon of dense water formation which is the only mechanism for the ventilation of the deep waters of the entire western mediterranean. it was observed that the deep waters can be formed 1) in a preconditioned open sea area and 2) on the shelf with a subsequent cascading down the slope. there are therefore two modes whose interannual monitoring is necessary to understand the evolution of mediterranean deep waters and validate ocean numerical models of the region. the lion mooring is deployed and maintained since 2007. it aims to observe the winter dense water formation affecting the north-western mediterranean sea water circulation and deep-sea ecosystem (physical data). the mooring is deployed near the odas meteorological surface buoy (odas lion, meteo france) and integrated in the moose network since 2010. it is part of the fixo3 and oceansites systems.

狮子锚泊位于狮子湾中心，此处冬季发生着最大的开阔海域对流之一。这一开阔海域对流是一种活跃的垂直混合过程，涉及整个地中海北部，并可深入至狮子湾深处（甚至可能触及底部，约2500米），这是由于冷而干燥的米斯特拉尔风和特拉蒙塔纳风的作用。这是形成密集水体的现象，它是整个西地中海深水通风的唯一机制。观测表明，深水可以在1）预先设定的开阔海域区域和2）大陆架上形成，随后沿着斜坡倾泻而下。因此存在两种模式，对它们的年际监测对于理解地中海深水的演变以及验证该区域海洋数值模型至关重要。狮子锚泊自2007年起部署并维护。其目的是观察影响西北地中海海水循环和深海生态系统的冬季密集水体形成（物理数据）。该锚泊位于奥达斯气象表面浮标（奥达斯狮子，法国气象局）附近，并于2010年纳入MOOSE网络。它是FIXO3和OCEANSITES系统的一部分。
