The city of Venice, capital of the Veneto Region is northern Italy, appears as a fish-shaped white island in the Venetian Lagoon along the Adriatic Sea. The city actually stretches across 118 small islands in the marshy lagoon.Visible on the Italian mainland across from the island is the city of Mestre.

The saltwater lagoon itself stretches along the shoreline between the mouths of the Po and the Piave Rivers. Here, the Piave can be seen flowing towards the Adriatic north of the lagoon. It begins in the Alps and flows southeast for 220 km (135 miles) into the sea.

The River Po meanders its way eastward across northern Italy, spilling greenish sediments through its delta into the Adriatic Sea. These sediments flank the coastline from Venice, north of the delta, to Ancona (in the bottom right corner of the full image). Also visible in the full image is the city of Trieste, near the border with Croatia, in the upper right.

To the north, the blue waters of Lake Garda are visible above the River Po at the foot of the Alps. Little snow can be seen on the mountains due to the warm summer temperatures. To the south, below the Po, the Apennines are also visible

Charlotte Harbor Estuary, Florida

Peace River and the Caloosahatchee River flow across the state of Florida into the Gulf of Mexico (lower left quadrant). The Peace River (left, above center) flows first into the Charlotte Harbor Estuary, a natural estuary spanning the west coast of Florida from Venice to Bonita Springs.

The Charlotte Harbor Estuary is classified as a bar-built estuary, formed when sandbars build up along the coastline. The sand bars block the waters behind them from the sea. Such estuaries are tend to be shallow with minimal tidal action.

The estuary is one of the most productive wetlands in Florida; however, it is also a threatened ecosystem resulting from the rapid increase of growth and development, poor land use policies, and the overuse of natural resources.

The Caloosahatchee River (south of Peace River) is also part of the estuary’s watershed and is connected to it via Pine Island Sound. It drains rural areas on the northern edge of the Everglades, northwest of Miami. An important link in the inland waterway system of southern Florida, the river forms a tidal estuary along most of its course and has recently become the subject of efforts to restore and preserve the Everglades.

Visible in the upper right corner is Lake Okeechobee, which is artificially connected to the Calossahatchee River and another lake, Lake Hicpochee, through the Caloosahatchee Canal.

This canal allows continuous navigation from the Caloosahatchee to the Okeechobee Waterway system; however, the canal and the use of the river’s water supply for urban and agricultural purposes, have substantially diminished the river’s flow levels. This has, in turn, reduced the water supply to the Everglades.

Plume of Dust Below Italy

A plume of dust from the Middle East or Northeastern Africa sweeps under southern Italy, over Malta, around Sicily and over the tip of Tunisia (bottom left).

It then curves upwards, passing between Sicily and Sardinia, and over part of the latter, before finally reaching the central Italian coastline.

In the full image, sediments can be seen hugging the southern and eastern shores of Sicily, as well as those of the Gulf of Tunis. The coastline of mainland Italy, is mostly clear, except for an outpouring of sediments around the mouth of the River Po and Venice (upper left).

Green sediments extend outward into the Adriatic Sea from the mouths of the River Po on Italy’s eastern coast.  The River Po has a drainage area of 71,000 km² and is the longest river in Italy.

The Po flows 652 km (405 miles) (or 682 km by considering the length of the system from the source of Maira River, a right side tributary) eastward across northern Italy.

It begins by Monviso (in the Cottian Alps) and ends in the Adriatic Sea near Venice (farther north along the coastline).

Near the end of its course, the River Po creates a wide delta with hundreds of small channels and five main ones, called Po di Maistra, Po della Pila, Po delle Tolle, Po di Gnocca and Po di Goro.
