Characterizing coastline changes and coastal hazards in the Canadian Arctic community of Grise Fiord

RBRvirtuoso3 logger in artic

Grise Fiord, located on Ellesmere Island in Nunavut, is the northernmost community in Canada’s Arctic and home to approximately 130 people. Over the last 20 years, community members have noticed significant changes to their coastline and increasing numbers of storm impacts. To better understand these changes and how they may need to adapt, they are collaborating with Dr. David Didier, … Read More

RBRcoda³ sensors added to Sofar Ocean Smart Mooring Platform

RBRcoda³ sensors added to Sofar Ocean Smart Mooring Platform

Sofar’s new Smart Mooring is an environmental monitoring tool capable of measuring a wide variety of parameters with a single universal interface.  Sofar has partnered with RBR to provide high-accuracy RBRcoda³ sensors to measure pressure, temperature, or dissolved oxygen along the smart mooring line and at the bottom.  Initial projects will focus on using the RBRcoda³ D pressure sensors for realtime measurements … Read More

RBRquartz³ Q bottom pressure recorders resolve small-scale changes in water level across a coral reef to determine roughness over complex terrain

RBRquartz³ Q bottom pressure recorder

In March 2017, a team from Stanford University deployed five RBRquartz³ Q bottom pressure recorders on the coral reef off the coast of Ofu, a South Pacific island of American Samoa, to resolve centimeter-scale changes in water surface height over the reef. The measurements they collected support the development of a comprehensive understanding of drag over complex terrain. Quantifying drag … Read More

RBR pressure sensors deployed to investigate ship wakes along the St. Lawrence Seaway

St Lawerence Seaway

The St. Lawrence Seaway has for sixty years provided a critical shipping route that connects the Atlantic Ocean to the Great Lakes. By a series of canals and locks built between 1955 and 1959, the Seaway covers 3,700km, from the Atlantic Ocean to the western limit of Lake Superior. It supports ships up to 225m long and with up to … Read More

Wave data and modelling inform harbour planning in southern Nova Scotia

oceanographer holding a depth sensor

The small fishing harbour of Lower Sandy Point, near the southern tip of Nova Scotia, was modified to reduce the agitating effects of swell. Breakwaters were added, nearly enclosing the harbour. The resulting structure – approximately in the shape of two backward Ls with an opening between their bases – successfully reduced the swell, and, several times each year, in … Read More
