Low/High Tides

After learning about tidal waves and their lunar schedule it made sense why cruise ships have limited* activities and stops they make depending on the time of day. If these massive cruise ships were to blindly sail into the coasts and any given time they could find themselves in a real pickle. They benefit from having this knowledge so that they can make their drop offs of vacationers on islands at a more precise time. This allows the vacationers to plan around a time approximation so they can plan activities before they get to the island.

Blue Planet: Coasts

PUFFINS

                          These Puffins live near Iceland and breed on large cliffs along the coast. One of the most visited cliff by these birds is the Hornbjarg cliff. Over half of the world population of the Atlantic Puffin breeds in Iceland. Huge numbers of birds gather together to breed at cliffs where its less likely predators can easily prey on their young. If and when a predator does show interest in the cliff where the birds have nested, they flee in packs in hope to confuse it. 

Blue Planet: The Coral Seas

A lot of sea creatures benefit from living on other animals and vice versa. One relationship that was particularly interesting was the microscopic shrimp that lived in the tunnels inside of a particular coral. The shrimp would protect the coral by snipping at intruders and the coral would provide the shrimp with everything they would need to live without leaving its tunnels.

The shrimp are nearly transparent.
This is the Queen shrimp with all the itty babies!! 

World Currents

Part 1. The pressures that control the winds are caused by heat differences in the air. Water currents are directly related to the wind currents when it comes to direction of flow. The warm air is pushed upwards as the cooler air is forced down creating a circular rotation of winds. This friction is what causes the water currents.

Part 2. The shoes got interlocked in the currents that eventually traveled to the shore.
