New aquatic tools: seismic oceanography, and a new method to measure lagrangian exchange

我的研究有三个新的探索，名为地震海洋学（提供洋流，漩涡和波浪的详细图像），幼虫运输和差异混合（可能影响我们的海洋气候模型）。 我会告诉你追踪幼虫的新方法克里斯·塔格特和我正在开发一种简单、便宜但非常有效的系统，用于确定洋流可以携带鱼类和珊瑚卵等小物体的位置。 了解水流携带幼虫的位置和速度，就像了解种子可以吹到哪里一样，是它们生活史中的一个重要因素。 例如，珊瑚礁对疾病、漂白或风暴造成的物理损害的敏感性，关键取决于珊瑚礁能否从邻近珊瑚礁获得幼虫。 一个健康的珊瑚礁要离患病的珊瑚礁有多近才能成功地补充营养？ 鱼类和龙虾种群也存在类似的问题。该系统简单而优雅：我们将许多含有磁铁矿的小塑料颗粒释放到水中。 这些颗粒像幼虫一样漂移，由于磁铁矿的存在，它们将被先前停泊在幼虫可能漂移的地方的水下磁铁收集。 每个收集器捕获的颗粒数量提供了重要的信息：珊瑚幼虫从X点漂到A、B、C等点的可能性有多大？ 该系统还有许多其他潜在的应用，包括水产养殖（贻贝苗如何到达贻贝养殖场？）和土木工程（在城市的暴雨系统中，暴雨水流到哪里，速度有多快？）。

My research has three new explorations, titled seismic oceanography (which gives detailed images of ocean currents, eddies and waves), larval transport, and differential mixing (which could affect our ocean climate models).  I will tell you about new ways to trace larvae. Chris Taggart and I are developing a simple, inexpensive, but very effective system for determining where ocean currents can carry small objects like fish and coral eggs.  Knowing where and how fast currents can carry larvae is, like knowing where dandelion seeds can blow, an important factor in their life history.  For example, the sensitivity of a coral reef to disease, bleaching, or physical damage from storms depends critically on whether the reef can be replenished with larvae from adjacent reefs.  How close must a healthy reef be to successfully replenish a diseased one?  Similar questions occur for fish and lobster populations. The system is elegant in its simplicity: we release into the water many small plastic particles containing magnetite.  These particles drift like larvae, and because of the magnetite, they will be collected by underwater magnets previously moored where larvae might drift.  The number of particles caught in each collector provides the important information: how likely is it that coral larvae can drift from point X to points A, B, C,  and so forth?   The system has many other potential applications, including aquaculture (how does mussel spat get to mussel farms?) and civil engineering (where and how fast does storm water flow in a city's storm system?).
