Phenology image time series of Silene aculis and Dryas octopetala from Bjørndalen, Spitsbergen, Svalbard, Norway. From Jun-Aug 2019, 2020, and 2021

Created in collaboration with Thomas T. Høye, as a part of Bjørndalen Integrated Gradients (BIG) with the support of the Olav Thon foundation and the University Centre in Svalbard. The aim of the series is to get data on flower – pollinator interactions, but the series also gives detailed information on the flowering phenology of the plants.
The series consists of photographs taken 1 meter above a plant (either S. aculis or D. octopetala) at a 90° downwards angle. Photographs were taken at 1-minute intervals*, using a Wingscapes BirdCam Pro mounted on a costume made quadpod. The dataset contains images from 3 summer (Jun-Aug) field seasons in 2019, 2020 and 2021. In the summer of 2019, 8 individuals of S. aculis and D. octopetala were photographed. In the summer of 2020 and 2021 10 individuals of S. aculis and 8 individuals of D. octopetala. The same individuals were used in all seasons, with an exception for camera placement of D. octopetala changing from 2019 to 2020. Metadata of photographs also contain temperature readings.
*Parts of the series contain images at lower intervals, but no during flowering.

本数据集由Thomas T. Høye合作完成，作为比约恩达伦综合梯度（Bjørndalen Integrated Gradients, BIG）研究项目的一部分，得到了奥拉夫·松基金会（Olav Thon foundation）与斯瓦尔巴大学中心（University Centre in Svalbard）的支持。本系列数据集的核心目标为采集花卉与传粉者互作数据，同时亦可提供供试植物的开花物候详细信息。该系列影像均以垂直向下90°的角度、距供试植物1米的高度拍摄，拍摄对象为S. aculis与D. octopetala两种植物。拍摄采用搭载于定制四脚架的Wingscapes BirdCam Pro型相机，以每分钟1帧的间隔连续拍摄*。本数据集涵盖2019、2020及2021年三个夏季（6月至8月）的野外调查季影像。2019年夏季，共拍摄了8株S. aculis个体与8株D. octopetala个体；2020年与2021年夏季，分别拍摄了10株S. aculis个体与8株D. octopetala个体。所有调查季均使用同一批供试个体，仅2019年至2020年期间，D. octopetala的相机安装位置有所调整。照片元数据中包含温度读数。*需注意，部分影像序列的拍摄间隔长于1分钟，但此类场景均未覆盖植物的开花期。
