Los Angeles and Long Beach are home to two of the busiest ports in the world, with over 6,500
vessels arriving and departing each year. Many of these commercial ships pass through the Santa
Barbara Channel and sanctuary, which may pose a collision threat to large species of whales. In
the fall of 2007, five blue whale fatalities were confirmed in the Santa Barbara Channel, with
the cause assumed to be from commercial vessel strikes. Although this was an unusually high
number, the incident was a serious concern for the sanctuary. To address this issue, Channel
Islands National Marine Sanctuary has continuously engaged in projects that involve collaboration
with the shipping industry, governmental agencies, non-profits, and other key stakeholders with
the goal of protecting whales while ensuring vibrant maritime commerce.
Whale species and abundance varies seasonally in the Santa Barbara Channel, so mariners should
exercise caution accordingly. From November to May, approximately 19,000 gray whales migrate
along the coast both nearshore and offshore. Endangered humpback, blue, and fin whales are present
in their greatest numbers from June through November. In addition, several other species such as
sperm whales and orcas are also occasionally seen in the Channel at various times throughout the year.
2016 WHALE ADVISORY AND VOLUNTARY SLOW SPEED ZONE TO REDUCE THE IMPACT OF SHIP STRIKES ON WHALES - NOW IN EFFECT
Vessels transiting the area between Point Arguello and Dana Point, including the Traffic
Separation Schemes in the Santa Barbara Channel and San Pedro Channel, from June through
November, should exercise caution and reduce speed. These areas contain populations of
endangered blue, humpback and fin whales that are federally protected under the Federal
Endangered Species Act (16 U.S.C. 1538 et seq.), the Marine Mammal Protection Act (16
U.S.C. 1361 et seq.), and the National Marine Sanctuaries Act (16 U.S.C. 1431 et seq.).
NOAA strongly recommends that vessels 300 gross registered tons or larger transiting the
Santa Barbara Channel Traffic Separation Scheme between Carrington Point, Santa Rosa
Island and Diablo Point, Santa Cruz Island, do so at speeds not in excess of 10 kts due to
endangered whales in the area. Please report any collisions with whales or any observed
injured or dead whales to NOAA at 877-SOS-WHALe (877-767-9425) or to the U.S. Coast Guard
on VHF Channel 16.
NOAA is asking for the public's help in tracking whales. If you see whales, please record
the date and location, the number of whales, the species (if known) and a description of
the animals. Please email
You can also report whales through WhaleAlert, a free application available at

CHANNEL ISLANDS REGION INCENTIVE-BASED VESSEL SPEED REDUCTION PROGRAMS 2014 AND 2016
In 2014, in partnership with local agencies and non-government organizations, Channel
Islands National Marine Sanctuary launched a trial incentive program to slow ships down in
the Santa Barbara Channel to reduce air emissions and reduce the likelihood of fatality
from a ship strike to endangered whales in the region. Seven global shipping companies
participated in 2014 and agreed to slow 27 transits to 12kts or less from July through
November in the Traffic Separation Scheme. This 2014 trial program not only demonstrated
the willingness of shipping companies to participate in a voluntary, non-regulatory,
non-port program, but also set the stage for a larger-scale program in 2016. Currently
underway, this year's vessel speed reduction program is largely modeled of off the 2014
trial, but has been expanded spatially to include a whale-safer transit zone south of the
islands as well as scaled-up fiscally to provide financial incentives for more than 65
transits to-date. For more information on the 2016 Vessel Speed Reduction Zone, please
contact Sean Hastings at email@example.com.
Mobile Apps Improve Collection of Real-Time Whale Data
Two innovative mobile applications (apps), Spotter Pro and Whale Alert, empower the public to
contribute to the protection of West Coast whales. The apps can be downloaded on smartphones and
tablets, and allow users to report whale sightings in real time. Spotter Pro has been designed for
specially trained observers, and Whale Alert is for all users. Download the app and find out more

Many partners assisted with app development and procurement of hardware, including: Office of
National Marine Sanctuaries, Cordell Marine Sanctuary Foundation, National Marine Sanctuary
Foundation, NOAA Fisheries, Point Blue Conservation Science, Conserve.IO, Pacific Merchant Shipping
Association, International Fund for Animal Welfare, and U.S. Coast Guard.
Santa Barbara Channel Traffic Separation Scheme Amendment
On June 1, 2013, the International Maritime Organization (IMO) amended the Santa Barbara Channel
Traffic Separation Scheme (TSS) and the approach to the ports of Los Angeles and Long Beach.
The TSS amendment reduced the width of the separation zone from 2 nautical miles (nm) to 1 nm by
shifting the inbound south lane shoreward and away from known whale concentrations. The outbound
north lane remained unchanged. Narrowing the separation zone is expected to reduce co-occurrence of
ships and whales while maintaining navigational safety.
