Iceberg Oscillations and Ocean Waves

Almost Periodic Oscillations and Waves

Links between ocean temperature and iceberg discharge during Heinrich events

Palaeoclimate records have revealed the presence of millennial-scale climate oscillations throughout the last glacial period1. Six periods of extreme cooling in the Northern Hemisphere—known as Heinrich events—were marked by an enhanced discharge of icebergs into the North Atlantic Ocean2,3, increasing the deposition of ice-rafted debris2. Increased sliding at the base of ice sheets as a result...

Ocean Waves Workshop 2015

The present study investigates the conspicuous shortcomings of the whitecapping dissipation model implemented in WAM Cycle 4.5 [1], following the lead of the work of [2] and [3]. Its dependence on an overall wave steepness unavoidably yields systematic errors when more than one wave system is propagating. The distinctive, complex orography of the Catalan littoral and the fact that the Mediterra...

Waves in the Ocean

In this document we will discuss three types of waves: wind-driven waves, tides and tsunamis. When the wind blows on the surface of the ocean it produces ripples, waves, and swell. Gravitational forces (mostly from the moon and sun) plus centrifugal forces in the solar system produce tides. Tectonic forces such as earthquakes that cause vertical displacements of the ocean floor, submarine volca...

An Analysis of Iceberg Profiling Strategies using Unmanned Ocean Systems

With the offshore development off the Newfoundland and Labrador coast, the environment becomes the key factor to the production. Each year hundreds of icebergs depart from the Greenland and drift towards the Newfoundland and Labrador. Icebergs in the vicinity of the offshore structure have a potential of causing production downtime, scouring the pipeline on the sea floor, and destroy the infras...
