15th International Symposium on Earth Tides

"Probing the Earth at Subseismic Frequencies"

2-6 August 2004



The 15th international Symposium on Earth Tides will be held in Ottawa, Canada’s Capital, from 2-6 August 2004. Ottawa is the heart of Canada, and much more than just a beautiful and spectacular city. With its neo-Gothic style and spirit, Ottawa straddles the border of the provinces of Ontario and Quebec exactly where Ottawa, Gatineau and Rideau rivers converge. Ottawa is the cultural and festival city with the highest concentration of museums in Canada. Parklands, gardens, trails, recreational pathways, historic monuments and grounds, and the Rideau Canal offer visitors an unsurpassed blend of national pride and French and English culture.

The National Arts Centre (NAC) will be the venue of the conference. It is among the largest performing arts complexes in Canada and is situated in the heart of the nation's capital across from Confederation Square and Parliament Hill, right next to Rideau Canal. NAC is unique, for it is the only multidisciplinary and bilingual performing arts centre in North America and features one of the largest stages on the continent.


 Plan your trip to Ottawa, Make your stay unforgettable!

The technical program allows the delegates to indulge into a variety of activities outside the busy hours of the symposium. Ottawa can certainly satisfy any interest in culture, history or simply natural outdoor attractions. And all these just minutes from the National Arts Centre!  Take a relaxing walk at the Byward market,  visit the Parliament Hill, take a tour around the city with the double decker bus or on a boat, board on the steam train for a dream journey into the past, and visit the over 80 museums, galleries and theatres. The nearby Gatineau National Park with the many fantastic trails offers a multitude of outdoor activities and natural wonders in every season. Night clubs, fine dining and Le Casino du Lac-Leamy can complete your day activities but don’t forget to come to the conference in the morning…

The weather in August is very pleasant with an average minimum of 14ºC and average maximum of 25ºC. You may need a light jacket early in the morning or late afternoon if you’re planning to enjoy the great outdoors, the cafés and restaurant patios. An umbrella may be needed occasionally… These predictions are based on long records after heavy smoothing with a boxcar in the time domain… occasional spikes, offsets, noise, and unusual drifts have not been taken into consideration… but you know how to deal with them!
