Visual observations recorded during the Antarctic blue whale voyage to the Southern Ocean 2013

The ‘Logger’ data entry system was developed by the International Fund for Animal Welfare (IFAW) and is a flexible system to record information during a voyage. This system was the primary data entry system for the voyage and all events were recorded in Logger’s database.The logger access database contains all data collected throughout the Antarctic blue whale voyage related to:Observer effort (effort status, event, number of observers and locations, ship guide and data logger)Cetacean sightings and resightings (time, sighting number, sighting platform, estimate distance, binocular reticles, angle, species, sighting cue, heading, estimate of number of individuals, observer of sighting, behaviour, pod compaction, comments)Sonobuoy deployments (time, sonobuoy number, notes)Environmental observations (sightability, sea state, swell, weather, cloud cover, visibility, intensity, glare, ice, sea surface temperature)GPS data (time indexed NMEA feed)CTD deployments (time, notes)Biopsy events (time, success, sample number, reaction, attempts, dart recovery, notes)

‘Logger’数据录入系统由国际动物福利基金会（International Fund for Animal Welfare, IFAW）开发，是一套可灵活适配航次期间信息记录需求的系统。该系统为本次南极蓝鲸航次的核心数据录入工具，所有事件均被存档于Logger数据库中。Logger访问数据库涵盖本次南极蓝鲸航次全程采集的全部相关数据，具体包含以下类别：观测员作业情况（作业状态、事件类型、观测员数量与作业位置、船舶向导与数据录入员信息）、鲸类目击与重目击记录（时间、目击编号、目击平台、估算距离、双筒望远镜十字标线读数、角度、物种、目击线索、航向、个体数量估算、目击观测员、行为、群体紧凑度、备注）、声呐浮标布放记录（时间、声呐浮标编号、备注）、环境观测数据（可见度、海况、涌浪、天气、云量、能见度、光照强度、眩光、海冰、海表温度）、GPS数据（时间索引的NMEA数据报文）、温盐深仪（CTD）布放记录（时间、备注）、组织活检事件（时间、采样成功率、样本编号、动物反应、尝试次数、飞镖回收情况、备注）。
