Book Description
The U.S. Geological Survey (USGS), Esri, the Group on Earth Observations (GEO), and the American Association of Geographers (AAG) are pleased to present A New Map of Global Ecological Marine Units - An Environmental Stratification Approach. This publication presents maps, data, and a web-based explorer application from a first-of-its-kind effort to partition the ocean into physically and chemically distinct volumetric regions called ecological marine units (EMUs). The EMUs were mapped from sea surface to seafloorin a true three-dimensional characterization of the oceanic water column. The EMUs were developed in a public/private partnership between USGS and Esri, in a collaboration that included a steering committee of international marine scientists. The work to delineate the EMUs follows the development of an analogous global ecological land units (ELUs) product also developed by the ESGS/Esri team, using a similar stratification-based mapping approach. Like the ELUs, the EMUs were commissioned by the GEO as part of a global ecosystem mapping initiative. With this Special Publication, AAG recognizes the work as a contribution to understanding the physical and ecological geography of the Earth.

Book Description
Terrestrial Ecosystem Research Infrastructures: Challenges and Opportunities reveals how environmental research infrastructures (RIs) provide new valuable insights on ecological processes that cannot be realized by more traditional short-term funding cycles and are integral to understand our changing world. This book bonds the latest state-of-the-science knowledge on environmental RIs, the challenges in creating them, their place in addressing scientific frontiers, and the new perspectives they bear. Each chapter is thoughtfully invested with fresh viewpoints from the environmental RI vantage as the authors explore and explain many topics such as the rationale and challenges in global change, field and modeling platforms, new tools, challenges in data management, distilling information into knowledge, and new developments in large-scale RIs. This work serves an advantageous guide for academics and practitioners alike who aim to deepen their knowledge in the field of science and project management, and logistics operations.

Book Description
A decade of technological advances and research on the human microbiome has re-defined our understanding of biological systems, and now offers diagnostic tools and new approaches to human health. Likewise, marine ecosystems are driven by their microbiome, the ensemble of microscopic organisms that inhabit the water column, sediments and aquatic organisms, and regulate most fluxes of energy and matter. While the human microbiome is composed principally of bacteria, the marine microbiome has a much broader ensemble of microscopic organisms with sizes spanning from viruses of a few tens of nanometres to metazoans of several centimetres. Advances in high throughput imaging and sequencing are emerging in aquatic science, providing important insights into ecosystem structure and functions, and contributing to develop new indicators of ecosystem health and potential hazards to living resources and humans. A number of research exploration and monitoring programs such as the Tara Oceans global expedition and the Marine Biological Observing Network (MBON), and the rising popularity of environmental DNA (eDNA) already led to a wealth of data. However, the wide range of methodologies used in this early exploration phase poses a challenge to integrative studies, prompting community responses such as the Genomic Standards Consortium. This Research Topic will foster cross-community exchange of standards and best practices. It is an opportunity for the different communities working on marine microbiomes to discuss the advantages and the limitations of their sampling and analysis methods. The collection of papers will constitute a knowledge base aimed at (1) addressing the integration of existing observations from heterogenous methods and data types, and (2) working towards cross-communities standards and best practices for future observations and experiments. This Research Topic will publish comprehensive methodological papers that review a sufficiently large body of field or experimental work. Supporting (meta)data, such as environmental context, sampling materials, sample treatments, extraction and imaging yields, must be provided and should preferably be uploaded to an online sample registry such as BioSamples. Protocols and analytical methods should preferably be uploaded to an online repository such as Protocols.io. We welcome contributions from communities working in different environments: · focus on marine systems, but also interested in estuarine and freshwater systems · coastal, open ocean and deep-sea regions · benthic, pelagic and aerosol environments We strongly encourage contributions from communities involved in: · networks of local observatories and long-term monitoring programs · regional & basin-scale surveys, and global expeditions · biodiscovery linked to economic sectors such as pharmaceutics and bioengineering · environmental and health assessments linked to economic sectors such as aquaculture, fisheries, seabed mining, wind-farms, and oil and gas

Book Description
The Atlas of Ocean Wealth is the largest collection to date of information about the economic, social and cultural values of coastal and marine habitats from all over the world. It is a synthesis of innovative science, led by The Nature Conservancy (TNC), with many partners around the world. Through these efforts, we've gathered vast new datasets from both traditional and less likely sources.

Book Description
Geocomputation with R is for people who want to analyze, visualize and model geographic data with open source software. It is based on R, a statistical programming language that has powerful data processing, visualization, and geospatial capabilities. The book equips you with the knowledge and skills to tackle a wide range of issues manifested in geographic data, including those with scientific, societal, and environmental implications. This book will interest people from many backgrounds, especially Geographic Information Systems (GIS) users interested in applying their domain-specific knowledge in a powerful open source language for data science, and R users interested in extending their skills to handle spatial data. The book is divided into three parts: (I) Foundations, aimed at getting you up-to-speed with geographic data in R, (II) extensions, which covers advanced techniques, and (III) applications to real-world problems. The chapters cover progressively more advanced topics, with early chapters providing strong foundations on which the later chapters build. Part I describes the nature of spatial datasets in R and methods for manipulating them. It also covers geographic data import/export and transforming coordinate reference systems. Part II represents methods that build on these foundations. It covers advanced map making (including web mapping), "bridges" to GIS, sharing reproducible code, and how to do cross-validation in the presence of spatial autocorrelation. Part III applies the knowledge gained to tackle real-world problems, including representing and modeling transport systems, finding optimal locations for stores or services, and ecological modeling. Exercises at the end of each chapter give you the skills needed to tackle a range of geospatial problems. Solutions for each chapter and supplementary materials providing extended examples are available at https://geocompr.github.io/geocompkg/articles/.
