Why the Black Sea

A sea I have watched for more than three decades

The Black Sea has been at the centre of most of my professional life.

When I began working at UkrSCES in 1992, the sea was already undergoing profound environmental change. Since then, I have seen periods of degradation and recovery, changes in monitoring and research, new forms of international cooperation — and, eventually, the environmental consequences of war.

That long perspective has shaped how I think about the sea.

A sea that remembers change

The condition of the Black Sea today is the result of processes that have accumulated over decades.

Pollution carried by rivers, eutrophication, changes in marine communities, invasive species, fisheries, coastal development and climate variability have all left their mark.

Some changes can happen quickly. Recovery may take much longer.

This is why long-term observations matter. A single sample tells us what was present at one place and one moment. A record extending over decades can tell us how the sea is changing.

A shared sea

No national border divides the water itself.

Rivers, currents, pollutants and marine organisms connect different parts of the Black Sea. Environmental problems that begin in one area can become regional problems.

For this reason, cooperation around the Black Sea is not simply desirable — it is necessary.

Data need to be shared. Methods need to be comparable. Scientists need to be able to work across institutional and national boundaries.

The Black Sea during the war

The war has added a new and still incompletely understood layer of pressure on the marine environment.

Damage to infrastructure, military activity, oil and chemical contamination, debris and restrictions on observations have changed both the sea and our ability to study it.

At the same time, maintaining environmental observations during the war is important precisely because these records will be needed later to understand what changed, what recovered and what did not.

Looking towards recovery

For me, studying the Black Sea is therefore not only about documenting environmental damage.

It is also about preserving the knowledge required for recovery.

The observations we maintain today can help distinguish the consequences of war from longer-term environmental change and provide the scientific basis for future restoration and European marine environmental policy.

More than a research area

After more than three decades of working with the Black Sea, it is difficult for me to see it simply as a geographical research area.

It is where much of my scientific experience was formed, where many of my longest professional collaborations began, and where questions about science, environment and society continually meet.

The sea connects people, knowledge and a shared future.
