Biogeochemical and phospholipid-derived fatty acid (PLFA) composition of deep-water hexactinellid and demosponges from New Zealand collected during SONNE cruise SO254

During R/V Sonne cruise SO254 around New Zealand (January-February 2017), deep-sea sponges were incubated in-situ and ex-situ to measure oxygen consumption, inorganic nutrient fluxes, bacterial and phospholipid-derived fatty acid (PLFA) composition.
Here, we present sponge volume, sponge mass (wet mass, dry mass, ash-free dry mass), carbon and nitrogen content, and stable isotopic composition (δ13TC, δ13org. C, δ15N) of sponge tissue together with PLFAs extracted from sponge tissue.

在2017年1月至2月间，于新西兰周边进行的Sonne号航行任务SO254期间，对深海海绵进行了原位及离位培养，以测定其氧气消耗、无机营养物质的通量、细菌以及由磷脂衍生出的脂肪酸（PLFA）组成。在本研究中，我们呈现了海绵的体积、海绵的质量（包括鲜重、干重、无灰分干重）、碳氮含量以及海绵组织中的稳定同位素组成（δ13TC、δ13org. C、δ15N），同时还包括从海绵组织中提取的PLFAs。
