Paul G. Allen Seaview调查 - Manado North Sulawesi印度尼西亚
苏拉威西岛北部是世界上一些金属氧化物半导体的所在地t biodiverse coral reef habits–it’s no wonder the team from the Global Change Institute are here assessing coral reef health. This years mission, revisit 28 dive sites around the Bunaken National Park, Bangka Island, and the mainland coast of Northern Sulawesi to document change in coral coverage since their first survey expedition in 2014.
重新调查团队由澳大利亚昆士兰大学的一群珊瑚礁生态学家组成，其中包括全球变更研究所的6名核心成员，来自海洋机构的电影摄制组以及雅加达，曼纳多和玛纳多的Sam Ratulangi University的合作者来自巴拉塔曼·纳斯·邦肯（Balai Taman Nasional Bunaken）的官员也一直在支持这项研究。
全球变革研究所有六个核心成员，该研究所是澳大利亚昆士兰大学科学潜水团队的一部分：
• Prof Ove Hoegh-Guldberg – Director of the Global Change Institute
• Dr Emma Kennedy (from the UK) – scientific lead
•Anjani Ganase博士（来自特立尼达） - 现场科学家
•凯瑟琳·马基（Kathryn Markey）（来自澳大利亚） - 现场科学家和技术官员
•Dominic Bryant（来自澳大利亚） - 现场科学家
• Patrick Gartrell (from Australia) – field scientist
在与调查团队见面之前，我已经听说过XL Caitlin Seaview调查，并沿着他们的3D underwater landscape。I have also shared stories about theirfree coral reef image bank资源，因此，度过一个周末，为当前的Seaview调查探险及其在全球变更研究所的研究挑选大脑是一种令人难以置信的荣幸。
保罗·艾伦（Paul G.设备仍然相同，XL Caitlin Seaview Survey使用该技术来“科学地记录世界的珊瑚礁，并以高分辨率，360度全景的视野向所有人展示它们。”
Seaview Survey in Action
The team suits up, heading underwater for a 2km transect across a shallow coral reef. For each survey, there are two divers in the water both equipped with dive propulsion vehicles.
Named Seaview II (or SVII) for short, one of the scooters is equipped with a custom made bug eyed orb, which contains three high-resolution Canon 5D MarkIV cameras. The cameras are timed to fire syncronistically and collect up to 1000 images per dive (3000 between the device).
潜水员在礁石上方一米滑行，每3秒钟拍摄一次图像。每个调查沿礁石峰的8到10m深度之间，这是珊瑚生长最多产的区域。如果他们在此深度记录更改，您可能会期望在所有其他深度上进行更改。
The divers have a thin tether to a GPS tucked into a surface float, so that each image is geo-referenced in space and time. This allows the team to go back to the exact same spot that the team visited last time.
After the survey, the images can be stitched together to make panoramic images, 3D videos, or each quadrant can be analyzed for benthic composition. The current Paul G. Allen Seaview survey will use single images taken from the bottom camera, however, all the image data from the surveys are available to the public atglobalreefrecord.org。
Bunaken的珊瑚礁正式蓬勃发展
每天晚上，团队将“日子”图像下载到硬盘驱动器上，这将返回澳大利亚昆士兰州大学的全球变化研究所实验室。回到澳大利亚，研究人员使用图像识别技术来分析在探险期间产生的数千张图像。
在实验室中，他们通过复杂的计算机程序来运行图像，该程序可以自动检测到珊瑚礁构成珊瑚礁的生命珊瑚（百分比），藻类和其他生物。用于分析图像的机器还标识了珊瑚分类单元，提供了有关哪种珊瑚和藻类构成每个礁石的信息。
I spoke with Dr. Emma Kennedy and Prof. Ove Hoegh-Guldberg, between dives who were both optimistic for the resilience of coral reef in Sulawesi. Before running the lab-based analysis of the images they confidently told me the coral reef in Sulawesi have been spared the recent coral bleaching and ocean warming crisis, and that Bunaken’s coral reefs are officially thriving
What made this project so unique was that the same initiative surveyed the reefs in 2014 and so on this trip they were able to assess the same areas and compare data to give a factual analysis of change – not just speculation.
该团队中只有一名成员Dominic Bryant参加了2014年和2018年的调查。他说，他认为珊瑚覆盖物与他所记得的东西保持稳定 - 而且很明显，几乎没有漂白损坏的证据。现在，该团队将需要在布里斯班分析数据，以确保调查如何比较2014年至2018年之间。
Global Reef Record – Open Data
所有的图像和数据收集the Global Reef Record (www.globalreefrecord.org), and anyways is able to view and analyzed the data. I had never played around with this website before and boy oh boy are we more excited than ever to have such a resource available at my fingertips.
Through the free online portal you can transport yourself anywhere the team has surveyed, this included many off the beaten path reef scapes throughout the world.
Here’s a look survey date from曼卡岛，，，，北部苏拉威西大陆，，，，andBunaken Island National Park.You can choose to view the data as a single image quadrat, stitched 3D images and even shorter timelapse videos from the dive. There is even an image analysis function created showing percent cover of coral and other benthic organisms along the transect.
We want to think the team from the Global Change Institute for welcoming me on the expedition and answering my many questions andMurex Dive度假村苏拉威西。
