DOCUMENT TITLE The future 0 Tagging used to track marine animals and their behavior ie that is migratory behavior and things like that Challenges of studying the ocean The ocean is huge Ships are slow even the fastest ships are still not fast in relation to how much ocean it can cover 0 Major processes take thousands of years 0 Many organisms live deep below the surface Ship surveys Pros new high tech instruments including cameras robots and deep sea submersibles Cons 0 short duration daysweeks 0 can t predict events like earthquakes 0 very expensive sometimes costs 50000 for one day of work Satellite Observations o pros longterm continuous observation of the entire planet cons only observes events in shallow surface waters Drifters moorings and buoys Pros o longterm monthsyears o broad scale can drift across ocean basins sending data back via satellite 0 May need ships to deploy and recover 0 Limited battery life 0 Limited control over paths New autonomous technology UUVs and UAVs Pros 0 Collect data in all weather conditions 0 Control path of travel 0 Collect longterm data Cons 0 High individual cost around 10000 0 Limited data transmission 0 Limited deployment life Mobil realtime acoustics help avoid whale and ship collision 0 Electrical glider 0 have a predetermined track and they have a certain sound that they pick up based on which species they are trying to record 0 used to tell ships exactly which spots to cover to save travel time 0 Real time mooring DOCUMENT TITLE 0 Wave glider Ocean observations 0 Longterm xed offshore sites with extensive longterm oceanographic sampling for months years and decades 0 Pros 0 Fiber optic cables for power and data 0 Utilize any and all high tech devices 0 Collect longterm realtime data Cons o Expensive o In a single geographic location for each observatory Studying right whale behavioral ecology to aid conservation 0 Topics necessary for this research 0 Classi cation species identi cation 0 Oceanography tides weather conditions and water properties The Bay of Fundy One of the greatest tidal variations in the world up to 20m 0 Rapidly changing weather 0 Cold water even in summer lt50 degrees at surface 0 Technology data collection tools Hydrophone array underwater microphones amp video recordings Suction cup acoustics Longterm acoustic monitoring arrays o Impacts of human activities how does noise impact right whales Tag data for assessing noise compensation If you put a tag on a whale you can 0 Use as an individual ID 0 Detect noise level at the whale 0 Obtain precise timefrequency measurements Clicker questions 0 500 north Atlantic right whales are alive today 0 quotcall louderquot is not an example of how right whales have been observed to respond to noise in their environment
