Physical, chemical, and biological factors drive evolution in marine communities in the oceans and coastal waters. The life mission of any species is to eat, survive, and reproduce(Figure 14.31). These isolated groups, if they don't go extinct, become the nucleus of a subsequent population that may evolve into a new species over time, perhaps better adapted to expand their populations when environmental conditions become favorable. Charles Darwin's famous synopsis, survival of the fittest basically means: if you can't compete, your options are "adapt, move, or die!"

Encyclopedia of Marine Geosciences
This Encyclopedia comprises the current knowledge in marine geosciences whereby not only basic but also applied and technical sciences are covered. Through this concept a broad scale of users in the field of marine sciences and techniques is addressed, from students and scholars in academia to engineers and decision makers in industry and politics.
Globally growing demand of energy and mineral resources, reliable future projection of climate processes and the protection of coasts to mitigate the threats of disasters and hazards require a comprehensive understanding of the structure, ongoing processes and genesis of the marine geosphere. Beyond the “classical” research fields in marine geology in current time more general concepts have been evolved integrating marine geophysics, hydrography, marine biology, climatology and ecology. As an umbrella the term “marine geosciences” has been broadly accepted for this new complex field of research and the solutions of practical tasks in the marine realm.
Jan Harff is Professor of Geosciences and Seafloor Geology at the University of Szczecin, Poland. His previous research focused on sedimentary basin analysis at the Central Institute for Physics of the Earth (ZIPE, subsequently the GeoForschungsZentrum, GFZ), Potsdam, and marine geology at the Leibniz Institute for Baltic Sea Research Warnemünde and the University of Greifswald, Germany. He cooperates, on a permanent basis, with marine research institutes of the Chinese Academy of Sciences, Chinese universities and the Guangzhou Marine Geological Survey, Guangzhou, China. His research interests concern marine geology in general, sedimentology, coastal geology, palaeo-oceanography, palaeoclimatology, mathematical geology and basin modelling. In addition to having authored and co-authored numerous research papers and having served as editor of other scientific publications, he acted as corresponding editor of “Modeling of Sedimentary Systems” (Springer,1999) and “The Baltic Sea Basin” (Springer, 2011).
Martin Meschede is Professor of “Regional and Structural Geology” at the Institute of Geography and Geology, University of Greifswald, Germany. His research interests focus on geodynamic processes at plate margins, subduction, large igneous provinces, exhumation, paleogeography, paleoclimatology, basin evolution, and glacial tectonics. He participated in several marine research expeditions, among these are the Joides Resolution of IODP and a diving cruise with Shinkai 6500. Besides a number of scientific publications, he is author and coauthor of several textbooks on plate tectonics, structural geology, and regional geology of Germany.
Sven Petersen is a senior researcher at GEOMAR, Helmholtz Centre for Ocean Research Kiel in Germany. His research focuses on understanding the processes that form and change seafloor hydrothermal systems and associated mineral deposits with time. He participated in more than 30 research cruises to submarine hydrothermal systems in the Pacific, Atlantic, and Indian Ocean. Major aims of his research are to understand their chemical variability, the use of mobile drilling techniques and geophysical methods to investigate their sub-seafloor extent as well as the use of autonomous underwater vehicles for their exploration.
Jörn Thiede is the leader of the KÖPPEN-Laboratory of the Institute of Earth Sciences of Saint Petersburg State University. He worked 1967-1987 at the universities of Aarhus (Denmark), Bergen (Norway), Oregon State University in Corvallis (USA), Oslo (Norway) and Kiel (Germany) and learned to sail the world’s oceans to understand their history. Afterwards he pursued the foundation of GEOMAR. In 1997 he joined The Alfred Wegener Institute-Helmholtz Centre for Polar and Marine Research. In 2008 he served at the Geocenter Denmark as well as at UNIS (Longyearbyen/Svalbard) and in 2011 was invited to join the St. Petersburg

This type of paper provides an outlook on future directions of research or possible applications.
Editor’s Choice articles are based on recommendations by the scientific editors of MDPI journals from around the world. Editors select a small number of articles recently published in the journal that they believe will be particularly interesting to authors, or important in this field. The aim is to provide a snapshot of some of the most exciting work published in the various research areas of the journal.
This Issue aims to highlight the complex interplay among biological and physical dynamics which concur in controlling the development of shallow marine systems, as well as their potential flourishing or demise. Shallow-sea environments typically show variable hydrodynamic and biological factors which interact at various scales of time and space, influencing or driving the arrangement of ancient marine deposits. At present, the global warming effects and the direct human impacts are concentrated along coastal areas, causing multiple stresses (sea-level rise, increase of extreme events, potential acidification, pollution, exploitation of marine biological resources) and inducing sudden changes in the littoral biological and sedimentary systems.
Contributions by clastic and carbonate sedimentologists, ecologists, and biogeoscientists that focus on these complex dynamics are the most welcome for this Issue. Studies on ancient shallow-sea successions, present-day examples, and numerical-analogical approaches are encouraged, as are interdisciplinary contributions.

How this time is divided varies, and is dependent on courses you choose to study and nature of the topics explored.
Typically you will do 60 credits of study for each of the two semesters, usually three courses. This study time includes time allocated for self-directed learning as well as 'contact time' with staff, which could be through lectures, tutorials, practicals or field trips.
You should expect to commit to approximately 17 hours a week of lectures, tutorials, and practicals. This will depend on the option courses you choose, during the first two years (pre-honours).
You will be expected to spend more time on independent work and self-directed study, as you progress into the 3rd and 4th years of study (honours).
You will design and execute your project dissertation in your final year, with guidance from our expert academics - helping you develop skills to become a researcher in your own right.
Most lectures last 50 minutes and many are recorded to support the revision of the material covered. The main form of contact you will have with academic staff will be through lectures.
You will apply the knowledge acquired in lectures and tutorials through practicals. The skills you learn in practicals are transferable beyond the immediate course and can be applied:
Tutorials are a form of small group teaching that is facilitated by a tutor. Many courses include tutorials. Tutorials are an essential opportunity for you to:
- discuss specific topics in more depth
- develop skills in critical thinking
- communicate your understanding
- work as part of a team
- receive feedback
- ask questions
Field trips are a significant component of our Earth science degrees and are:
- hard work and fun (they will provide some of your most memorable moments)
- an excellent way to learn, enabling you to apply the knowledge and skills you have developed in lectures to real-world contexts
- part of your course (there are no additional costs)
You will need to be well-motivated and organised, emphasis is placed on independent work.
What skills will I learn?
You will develop a scientific understanding of environmental processes throughout the programme. In addition, programme academics will incorporate the latest research in the teaching you receive, and share their discoveries with you.
You will also cover core topics in modern environmental sciences in a variety of settings, including practical laboratory and fieldwork.
You could be assessing the water quality in a river in the highlands on one day and swimming in coral reefs collecting water samples on another.
You will enhance your ability to work independently and manage project work as the programme progresses.
Your training will also equip you with unique skills in problem-solving, making you ideally suited to work in environments where solutions to complex challenges need to be found (based on limited available data).
You will also develop a range of transferable skills, including:
- report writing
- oral presentations
- data analysis and interpretation
- critical thinking
- group working
How will I be assessed?

In pursuit of this mandate, the Centre creates a data bank and body of knowledge where concerns and challenges of investors, investigators and all other stakeholders interested in geo-scientific evolution, exploitation, development, vulnerability and management of Nigeria’s coastal and offshore environments are creditably catered for.
Capacity-building and research efforts of the Centre have been recently welcomed by Niger Delta University, University of Port Harcourt, Federal University Otuoke, AkwaIbom State University, Federal University of Technology Akure, and the International Council of Science Union (Regional Office for Africa), South Africa.
14.19: Evolution in Marine Environments - Geosciences
The Antarctic continent and surrounding oceans are key parts of the Earth System through the entire history of the Earth. The basement core of Antarctica comprises a suite of crustal blocks that were parts of various supercontinents (e.g. Rodinia, Gondwana). Their outcrops provide important insights into Earth processes. Sedimentary records on and around Antarctica also provide important insights into the history and natural variability of the earth's environments. The geological record can provide key insights into the evolution and processes of change in the Antarctic environment and the biota dependent on it. The geology of the ice sheet bed strongly influences ice behaviour and the development of the ice sheet from its inception. Geodetic and geophysical observatories can furnish a fundamental contribution to the study of geodynamics processes across the continent. The challenge of the next phase of Antarctic science will be to integrate all branches of science into a holistic understanding of Antarctica and its trajectory of change.
Geoscience Scientific Research Programmes:
Integrated Science to Inform Antarctic and Southern Ocean Conservation (Ant-ICON)
The Ant-ICON SRP will answer fundamental science questions (as identified by the SCAR Horizon Scan), relating to the conservation and management of Antarctica and the Southern Ocean and focus on research to drive and inform international decision-making and policy change.
INStabilities and Thresholds in ANTarctica (INSTANT)
The INSTANT SRP will address a first-order question about Antarctica’s contribution to sea level. It encompasses geoscience, physical sciences and biological sciences, of the way in which interactions between the ocean, atmosphere and cryosphere have influenced ice-sheets in the past, and what expectations will be in the future with a special focus on quantifying the contributions to global sea level change. They aim to quantify the Antarctic ice sheet's contribution to past and future global sea-level change.
