Welcome back to another episode of Earth from Space.

Part of the Frisian Islands,

a low-lying archipelago just off the coast of northern Europe,

is visible in this image captured by Copernicus Sentinel-2.

The Frisian Islands stretch from the northwest of the Netherlands

through Germany

to the west of Denmark.

Although theyre considered a single physical feature,

they are divided into West, East and North Frisian Islands

with the North Frisian Islands visible here.

The islands are split between Germany and Denmark.

There are four larger islands that make up the archipelago.

These are Sylt,

Fhr,

Amrum,

and Pellworm.

Sylt, the largest of the archipelago,

is around 100 sq km

and is known for its distinctive shape of its shoreline.

The islands extends more than 35 km in length

and, in some places,

is only 1 km wide.

A sandy beach stretches across the islands west coast,

however it has begun to erode owing to storm tides.

The northernmost island of Germany,

it is connected to the mainland by the Hindenburgdamm,

an 11 km-long causeway.

The Wadden Sea on the islands east side

is part of the Schleswig-Holstein Wadden Sea National Park

and has been a nature reserve and bird sanctuary since 1935.

The island of Fhr is called the Green Island

due to it being sheltered from the storms of the North Sea by its neighbouring islands.

The island of Amrum features an extended beach area along its west coast,

which faces the open North Sea.

The east coast borders to mud flats and tidal creeks of the Wadden Sea.

The three white islands are the North Frisian Barrier Islands.

These sand banks,

or shoals,

act as a natural breakwater for the smaller islands closer to land.

Just east of these lies the island of Pellworm.

North of Sylt lies the Danish islands of:

Rm,

Mand,

and, lastly,

Fan.

In the top-left,

a large algal bloom is visible in emerald green.

Harmful algal blooms caused by excessive growth of marine algae

have occurred in the North Sea in recent years,

with satellite data being used to track their growth and spread.

These data can then be used to help develop alert systems

to mitigate against damaging impacts for tourism and fishing industries.
