Plankton are organisms that in essence drift in the oceans. They range from microbial organisms to jelly fish and krill. Plankton have played a key role in planetary ecosphere functioning (having produced half of the atmospheric oxygen that we breath, and also most of the limestone and much of the non-coal fossil fuels). They continue to play an important role in climate change events, food sustainability (fisheries), down to local societal levels in harmful algal blooms and sea-snot (beach foam) events. This project will provide the foundation for pivotal developments in marine science, namely configuring plankton for the digital twins of the oceans. Digital twins (DTs) are computer-based analogues for real systems; well-known examples are flight simulators and many reality-based video game platforms. DTs are heavily used in engineering and in business, providing design and testing platforms. They are especially useful for 'what-if?' testing. However, it is critical that the end user has trust that the platform they are using does indeed describe a digital twin that would be deemed satisfactory to experts in the real system.This work comprises essential underpinning for the UK and international initiatives to produce within this decade digital twins of oceanic processes of societal importance, including the United Nations Digital Twins of the Oceans (DITTO) initiative. The idea behind DITTO, for example, is to see the generation of DT platforms, freely available to the public with a suitable graphic-user-interface, to support education, management and decision making. Some of these may be within game-like platforms to engage and inform the public about plankton (why their local beach is out-of-bounds due to harmful algal bloom or jelly-fish, for example), while other platforms will support science policy and management.Despite the critical importance of plankton in marine ecology, the current generation of computer descriptions ('models') provides only a poor caricature of the real organisms that is quite unsuitable for digital twin applications. The reasons for this include a lack of suitable data to directly support modelling, and a hitherto poor interaction between modelers and those empiricists who study real plankton. The project will work by exploiting 'expert witness validation', an approach similar to that of the famous Turing test for artificial intelligence, which aims to produce models that are sufficiently realistic in their behaviour that experts in the subject (plankton) cannot tell the difference. The project will work with experts in each plankton group to reach a consensus on what computer models of different plankton types should behave like such that they could be considered as a 'digital twin'. The one-year project will see the production of reference-type materials (such as check-lists, and example response patterns) to guide future development of plankton models, specifically for digital twin applications to ensure that the description of these organisms accords with the expectations of experts in the field.

浮游生物本质上是在海洋中漂流的生物。它们的范围从微生物到水母和磷虾。浮游生物在地球生态圈的运作中发挥了关键作用（产生了我们呼吸的大气氧气的一半，以及大部分石灰石和大部分非煤化石燃料）。它们继续在气候变化事件、粮食可持续性（渔业）、下至地方社会层面的有害藻华和海鼻涕（海滩泡沫）事件中发挥重要作用。该项目将为海洋科学的关键发展奠定基础，即为海洋的数字双胞胎配置浮游生物。数字孪生（Digital Twins，DT）是基于计算机的真实的系统的模拟;众所周知的例子是飞行模拟器和许多基于现实的视频游戏平台。DT在工程和商业中大量使用，提供设计和测试平台。它们对于“如果......会怎样”特别有用。测试然而，最终用户必须相信他们使用的平台确实描述了一个数字孪生模型，该模型将被认为是真实的系统中的专家满意的。这项工作为英国和国际倡议提供了必要的基础，以便在本十年内产生具有社会重要性的海洋过程的数字孪生模型，包括联合国海洋数字孪生模型（DITTO）倡议。例如，DITTO背后的想法是看到DT平台的生成，通过合适的图形用户界面免费提供给公众，以支持教育，管理和决策。其中一些可能是在类似游戏的平台内，以吸引和告知公众有关浮游生物的信息（例如，为什么他们当地的海滩由于有害藻华或浮游鱼而被禁止进入），而其他平台将支持科学政策和管理。尽管浮游生物在海洋生态中至关重要，当前一代的计算机描述（“模型”）仅提供了对真实的生物体的拙劣的讽刺，这非常不适合于数字孪生应用。其原因包括缺乏直接支持建模的合适数据，以及迄今为止建模者与研究真实的浮游生物的生物学家之间的互动很差。该项目将通过利用“专家证人验证”来工作，这是一种类似于著名的人工智能图灵测试的方法，其目的是产生行为足够逼真的模型，以至于该主题（浮游生物）的专家无法区分。该项目将与每个浮游生物群体的专家合作，就不同浮游生物类型的计算机模型应该表现出什么样的行为达成共识，以便它们可以被视为“数字孪生”。这个为期一年的项目将制作参考类型的材料（如检查表和示例响应模式），以指导浮游生物模型的未来开发，特别是数字孪生应用，以确保这些生物的描述符合该领域专家的期望。
