Jervis Bay Infauna Images

Geoscience Australia carried out marine surveys in Jervis Bay (NSW) in 2007, 2008 and 2009 (GA303, GA305, GA309, GA312) to map seabed bathymetry and characterise benthic environments through co-located sampling of surface sediments (for textural and biogeochemical analysis) and infauna, observation of benthic habitats using underwater towed video and stills photography, and measurement of ocean tides and wave-generated currents. Data and samples were acquired using the Defence Science and Technology Organisation (DSTO) Research Vessel Kimbla. Bathymetric mapping, sampling and tide/wave measurement were concentrated in a 3x5 km survey grid (named Darling Road Grid, DRG) within the southern part of the Jervis Bay, incorporating the bay entrance. Additional sampling and stills photography plus bathymetric mapping along transits was undertaken at representative habitat types outside the DRG.

This folder contains the images derived from benthic samples taken on the surveys GA0312, GA0315 and GA0309 aboard HMS Kimbla. These images formed the first point of reference in identifying subsequent specimens to save wear and tear on the specimens put aside as reference material. Four phylum folders exist within the main folder: Annelida, Crustacea, Echinodermata and Mollusca. The crustacea folder contains further folders, breaking the images into finer groupings. Images of taxa that do not fit in the four phylum folders are loose in the main folder.

澳大利亚地质调查局（Geoscience Australia）于2007年、2008年及2009年在新南威尔士州杰维斯湾开展海洋调查（项目编号GA303、GA305、GA309、GA312），通过同步采集表层沉积物（用于纹理分析与生物地球化学分析）及底内生物样品、采用水下拖曳式视频与静态摄影观测底栖生境、测量海洋潮汐与波浪诱导流，完成海底水深测绘并表征底栖环境。数据与样品采集工作由国防科学技术组织（Defence Science and Technology Organisation, DSTO）的“金布拉号”研究船（Research Vessel Kimbla）执行。本次调查的水深测绘、样品采集及潮汐/波浪测量工作主要集中在杰维斯湾南部一块3×5千米的调查网格（命名为达令路网格，Darling Road Grid, DRG），该区域涵盖海湾入口。此外，研究团队还在达令路网格以外的典型生境区域开展了额外采样、静态摄影以及沿航线的水深测绘工作。

本文件夹包含GA0312、GA0315与GA0309航次中采集的底栖样品所得图像，采集工作搭载于“金布拉号”皇家海军舰艇（HMS Kimbla）完成。这些图像是后续标本鉴定的首要参考依据，可有效减少作为参考材料留存的标本的损耗。主文件夹下设四个门级分类文件夹，分别为环节动物门（Annelida）、甲壳动物门（Crustacea）、棘皮动物门（Echinodermata）及软体动物门（Mollusca）。其中甲壳动物门文件夹下包含更细粒度的子文件夹，对图像进行细分归类。无法归入上述四个门级文件夹的类群图像将直接存放在主文件夹内。
