Jan-Feb 2024 Ocean glider observations in Greater Cook Strait, New Zealand

this dataset consists of a glider deployment in greater te moana-o-raukawa (cook strait) as part of the deepsouth national science challenge in aotearoa new zealand. this submission continues from previous deployments uploaded to seanoe (doi:10.17882/76530). survey uses a teledyne webb research slocum g2 glider equipped with a pumped seabird ctd to measure conductivity, temperature, and pressure, along with instruments to measure dissolved oxygen, chlorophyll-a fluorescence, backscatter at 470, 532, 660, and 700nm, chromophoric dissolved organic matter (cdom), and photosynthetically active radiation (par). part-way through the deployment, in order to save battery, the science package was turned on only during downcasts and these subsequently appear as empty casts in the dataset. science data were processed using the geomar glider toolbox (https://git.geomar.de/open-source/geomar_glider_toolbox). comparison with the previously-utilized socib (troupin et al. (2015), doi: 10.1016/j.mio.2016.01.001) toolbox shows negligible differences in outputs. data have been averaged into vertical bins of 1dbar (~1m). despite processing to minimize lag-error in salinity (following garau et al., 2011, doi: 10.1175/jtech-d-10-0503.1), some casts (n=10, out of 4246 total) were made empty after visual inspection in t-s space. oxygen data were lag-corrected, whereas other variables are presented as-is without further processing. depth-integrated water velocity derived from gps and dead-reckoning are included.

本数据集包含在大特莫纳-奥劳卡瓦（库克海峡）进行的滑翔机部署，该部署是新西兰奥塔哥南岛深南国家科学挑战计划的一部分。本提交延续了之前上传至Seanoe平台（DOI: 10.17882/76530）的部署。调查使用了配备有泵浦式海鸟型CTD的Teledyne Webb Research Slocum G2滑翔机，以测量电导率、温度和压力，并配备了测量溶解氧、叶绿素a荧光、470、532、660和700nm处的散射系数、有色溶解有机物（CDOM）以及光合有效辐射（PAR）的仪器。在部署过程中，为了节省电池，科学装置仅在下沉时开启，因此在数据集中这些数据表现为空沉。科学数据经过Geomar滑翔机工具箱（https://git.geomar.de/open-source/geomar_glider_toolbox）进行处理。与之前使用的SOCIB（Troupin等，2015，DOI: 10.1016/j.mio.2016.01.001）工具箱的比较表明，输出结果之间的差异可以忽略不计。数据已平均到1dbar（约1米）的垂直柱中。尽管经过处理以最小化盐度中的滞后误差（参照Garau等，2011，DOI: 10.1175/jtech-d-10-0503.1），但在t-s空间中进行视觉检查后，仍有10次（总数为4246次）的投掷数据被标记为空。氧数据进行了滞后校正，而其他变量则未进一步处理直接呈现。包含来自GPS和测程的深度积分水流速度。
