Respiration rate and ammonium excretion data for the squat lobster Pleuroncodes monodon measured during METEOR cruise M93

Sampling was conducted during RV Meteor cruise M93 in austral summer 2013 in an area from 11ºS to 14ºS and approximately 120 km offshore to within 10 km of the Peruvian coast. Specimens were collected using a Hydrobios Multinet Maxi (0.5 m2 mouth opening, 330 µm mesh size, 9 nets) and a WP-2 net (Hydrobios, 0.26 m2 mouth opening, 200 µm mesh size). P. monodon were identified according to http://researchdata.museum.vic.gov.au/squatlobster/delta/deltakey.html. Specimens were transferred into filtered, well-oxygenated seawater immediately after the catch and maintained for 4 to 16 hours prior to physiological experiments. Maintenance and physiological experiments were conducted at 13°C as the temperature observed at 100 to 200 m depth in the OMZ ranged from 13.7 to 12.7°C.本采样工作于2013年南半球夏季，搭载‘流星号’（RV Meteor）科考船执行M93航次期间开展，采样区域涵盖南纬11°至14°、离岸约120公里至秘鲁海岸10公里以内的海域。样本采集采用Hydrobios公司生产的Multinet Maxi多网采样器（口门面积0.5 m²，网孔孔径330 µm，内含9个采样网）及WP-2型网具（Hydrobios，口门面积0.26 m²，网孔孔径200 µm）。P. monodon的物种鉴定参照网址http://researchdata.museum.vic.gov.au/squatlobster/delta/deltakey.html完成。样本捕获后即刻转移至过滤且充氧的海水中，并在生理实验前暂养4至16小时。暂养操作与生理实验均在13℃条件下进行，此温度参考了氧最小层（Oxygen Minimum Zone, OMZ）100~200米水深处的实测水温范围（12.7~13.7℃）。
