Abstract

Geology is a core component of two major multidisciplinary seabed-mapping initiatives in Norway (MAREANO, Marine Base Maps for the Coastal Zone). Helped by Norway’s Nature Diversity Act, which acknowledges geological and landscape diversity alongside biodiversity, geological information has gained recognition nationally as part of an essential foundation for knowledge-based management, both in the coastal zone and offshore. Recently, international focus on the United Nations Sustainable Development Goals has led to the proposal of Essential Geodiversity Variables, a framework for geological (geodiversity) information, intended to stand alongside Essential Variables already defined for climate, biodiversity and oceans (limited to ocean physics, biochemistry, biology, and ecosystems). Here we examine to what extent map products from the Geological Survey of Norway generated under these multidisciplinary mapping initiatives fit within this framework of Essential Geodiversity Variables and how well it is suited to information on marine geodiversity. Although we conclude that the framework is generally a good fit for the marine-relevant Essential Geodiversity Variable classes (geology and geomorphology), we examine opportunities for further highlighting quantitative geodiversity information. We present preliminary examples of substrate diversity and morphological diversity and discuss our experience of geological mapping as part of multidisciplinary initiatives. We highlight many benefits, which far outweigh any perceived or real compromises of this approach in monetary, practical and scientific terms.
通过多学科测绘举措提供海底地理多样性信息:挪威的经验
地质学是挪威两个主要的多学科海底测绘举措的核心组成部分(MAREANO,海岸带海洋基础地图)。挪威《自然多样性法》承认地质和景观多样性以及生物多样性,在该法的帮助下,地质信息作为沿海地区和近海知识管理的重要基础,在全国范围内得到了认可。最近,国际社会对联合国可持续发展目标的关注导致提出了基本地质多样性变量,这是一个地质(地球多样性)信息框架,旨在与已经为气候、生物多样性和海洋(仅限于海洋物理、生物化学、生物学和生态系统)定义的基本变量站在一起。在这里,我们研究了挪威地质调查局在这些多学科测绘举措下生成的地图产品在多大程度上符合基本地球多样性变量的框架,以及它在多大方面适合海洋地球多样性信息。尽管我们得出的结论是,该框架通常很适合海洋相关的基本地质多样性变量类别(地质学和地貌学),但我们研究了进一步强调定量地质多样性信息的机会。我们介绍了基质多样性和形态多样性的初步例子,并讨论了作为多学科举措一部分的地质测绘经验。我们强调了许多好处,这些好处远远超过了这种方法在货币、实践和科学方面的任何感知或实际妥协。
