Long-term time-series of mesozooplankton biomass in the Gulf of Naples, data for the years 2001-2004

Total mesozooplankton biomass was measured as dry weight on a fresh sample. Samples were sieved on 200 ?m nitex, briefly rinsed with distilled water to remove salt, transferred on pre-weighted alluminium foil and placed in an oven at 60°C. The samples were weighted on a microbalance after 24 hours and again 2-3 times within the following seven days, until the weight was constant. This latter value was considered as dry weight.

本数据集以干重法测定新鲜样本中的总中型浮游动物（mesozooplankton）生物量。样本经200微米尼泰克斯（nitex）筛网筛分后，用蒸馏水短暂冲洗以去除盐分，随后转移至预先称重的铝箔上并置于60℃烘箱中。样本于24小时后使用微量天平称重，并在后续7天内重复称重2至3次，直至重量保持恒定，该恒定值即被认定为干重。
