Dry weight biomass measurements of net-collected mesozooplankton. Samples collected in the CCE-LTER region on Process Cruises from 2006 to the present. Summaries for each Lagrangian Cycle.

Mesozooplankton are collected with plankton nets (typically a 71-cm diameter, 202-um
mesh Bongo net) and samples flash frozen at sea in liquid N2 for subsequent shore-based
measurements of dry weight biomass. Measurements are made by weighing pre-tared Nitex mesh on
an analytical balance, for mesozooplankton size-fractionated into 5 different categories (>
0.2 mm, 0.5 mm, 1.0 mm, 2.0 mm, 5.0 mm). Biomass is expressed as dry mass of zooplankton per
m3 of water filtered, or when multiplied by the maximum depth of the tow, as integrated dry
mass of zooplankton per m2 of sea surface. Samples for dry weight biomass have been collected
on CCE-LTER Process Cruises since 2006 and these collections are ongoing.

中型浮游动物（Mesozooplankton）通过浮游生物网采集，通常采用直径71 cm、网目202 μm的邦戈网（Bongo net）；所获样品将在海上以液氮（liquid N2）快速冷冻，用于后续岸基干重生物量测定。测定时，将按尺寸划分为5个类群（>0.2 mm、0.5 mm、1.0 mm、2.0 mm、5.0 mm）的中型浮游动物置于预先完成去皮重校准的Nitex网布上，使用分析天平称重。生物量以单位过滤水体的浮游动物干质量为单位表示；若将该值乘以拖网最大水深，则可换算为单位海表面积的浮游动物累积干质量。自2006年起，研究人员已在CCE-LTER过程航次（CCE-LTER Process Cruises）中开展干重生物量样品采集工作，且该采样计划目前仍在持续进行中。
