DeepDyve eBooks - A Philosophical View of the Ocean and Humanity

Introduction

Omstedt, Anders

Pages: 1 –8

[This opening chapter introduces the threats that the ocean and its coastal seas face from strong anthropogenic pressures. The challenge of addressing these threats require a great change in human behaviour, as communicated by scientists and in the United Nations 2030 Agenda for Sustainable...

An Attempt to Connect to the Ocean

Omstedt, Anders

Pages: 9 –11

[In this chapter, the first connection with the ocean is through a dream image of a dead seabird that had ingested plastics. The senseless killing of a seabird is the theme of The Rime of the Ancient Mariner by Coleridge, illustrating how killing an albatross brought isolation and death in life....

Knowledge in Science and the Arts

Omstedt, Anders

Pages: 13 –19

[In this chapter, we examine our knowledge sources and the ocean reminds us that we each have both a brain and a heart. Humans have many different knowledge sources and ways of thinking. One way humans process life situations is through slow, analytical, calculative, and rational thinking, i.e.,...

Ice and Curiosity

Omstedt, Anders

Pages: 21 –27

[The objective of this chapter is to establish communication between marine science and the arts by giving the ocean a voice. The first topic is the dynamics and thermodynamics of sea ice and related threats due to global warming. When seen from the geophysical scale, sea ice is a beautiful and...

Stratification, Turbulence, and Services

Omstedt, Anders

Pages: 29 –33

[This chapter continues the dialogue between science and the ocean, starting with a concerned science view. A great fear is that global warming may reduce areas of sinking water, reducing ocean ventilation. The ocean responds with an image of a kelp forest—among the most beautiful and...

Currents, Circulation, and Vulnerability

Omstedt, Anders

Pages: 35 –40

[The ocean is never at rest. Currents, eddies, and turbulence change its conditions for life at different time scales in a beautiful and complex manner. Human misbehaviour is clearly seen in the waste, including plastic, from various sources that is transported all over the ocean by these...

Heat Balance, Water Temperature, and Interpretations

Omstedt, Anders

Pages: 41 –46

[The heat balance that determines the earth’s temperature represents an interesting and complex interplay between the sun, the earth, and our behaviour. The ocean plays many important roles in this, such as being the earth’s most important heat storage sink. Evaporation from the ocean surface due...

Water Balance, Salinity, and Belonging

Omstedt, Anders

Pages: 47 –51

[The water balance essential for transporting freshwater and maintaining ocean salinity is investigated here. The atmosphere transports freshwater towards the poles, and the ocean closes the cycle by transporting it back towards the equator. Most of the world’s freshwater is found in the ocean....

Oxygen, Life, and Partnership

Omstedt, Anders

Pages: 53 –56

[This chapter describes another essential chemical for life and for many biogeochemical processes, namely, oxygen. The oxygen concentrations in the ocean are declining, causing the spread of oxygen-free water. The reasons for this decline seem to be climate warming, increased nutrient transports...

Available

Plankton and Courage

Omstedt, Anders

Pages: 57 –61

[After discussing oxygen, we turn to the plankton that forms the basis of the marine food web. There are many different forms of plankton and with large genetic variation, giving plankton great resistance to environmental changes. Plankton provides extraordinary ecosystem services by taking up...
