They examined a half-million data points collected using a tool called a Secchi disk, as well as measurements of chlorophyll-a pigment produced by the plankton.

他们检查了50万个由一种被称为塞齐盘的工具所采集的数据点，并且测量了由浮游植物所产生的色素——叶绿素。

Why protect chlorophyll at a time when the tree is breaking it down to salvage as much of it as possible?

在树木将叶绿素分解，以尽可能多地将其回收的时候，为什么我们还要保护叶绿素呢？

The process of disassembly liberates chlorophyll from a molecular production-line called the electron-transfer system.

These areas are known as HNLC (high-nutrient, low-chlorophyll) zones and are thought to be caused by a scarcity of iron.

CNN: Topical waters

While typically monitored through satellite imagery direct validation of chlorophyll blooms at this resolution provides a groundbreaking link between scientific modeling and in-situ measurement of the Pacific Ocean.
