The Complexities of Arctic Maritime Traffic

In late August 2017, the Russian icebreaking liquefied natural gas (LNG) carrier Christophe de Margerie made headlines in maritime traffic news for a record-setting transit of the Northern Sea Route (NSR). The ship transited the 2,193 nautical mile NSR in just six days, twelve hours, and fifteen minutes. It completed the entire journey from Hammerfest, Norway, to Boryeong, South Korea, in nineteen days—nearly thirty percent faster than the traditional Suez Canal route. During the transit, the vessel averaged just over fourteen knots, remarkable given that part of the transit was through ice fields that were 1.2 meters thick.1)

Such an accomplishment has fueled optimism,

Of the hundreds of millions of tonnes of plastic waste we produce each year, it’s estimated that around ten million tonnes enters the ocean. Roughly half of the plastics produced are less dense than water, and so they float. But scientists estimate that there are only about 0.3 million tonnes of plastic floating at the ocean surface, so where is the rest of it going?

Consider the journey of a plastic fiber that’s shed from your fleece. A heavy rain washes it into a storm drain or a nearby river. Does the tiny fiber settle there? Or does the river carry it out to the coast where it lingers on the seabed?

INTRODUCTION

Nearly everyone who sails much has a clear image in mind of such weather phenomena as warm and cold fronts and highs and lows and roughly what to expect as they arch majestically across the daily weather maps in newspapers and the TV screen. It all seems easy to understand and forecasts are, at least somewhat more often than not, correct. But it’s the times that forecasts are not correct which most concern us when we’re at sea. There are so many variables which all together must be accounted for in order to arrive at an accurate weather forecast that we may as well forget about reaching that ideal in our lifetimes. One scientist pointed out years

Waves are one of the most beautiful and awe-inspiring natural phenomena. Glancing through the ocean, one can see innumerable waves as far as the vision can decipher.

They are in a continual set of motion – rising up, moving forward, splashing amongst themselves, losing their motion and then rising again. They are a treat to watch, and even better to play with.

They are the reason why beach-goers and surfers visit otherwise boring sea beaches. Yes, you heard me right! Imagine a beach, with no waves at all.

Sand and water will be all you’d be left with, which would be…pretty…..boring!

Sea waves are one of the beautiful natural marvels that excite us.
