SUPPLEMENTARY INFORMATION:

Background

    Section 117 of the Marine Mammal Protection Act (MMPA) (16 U.S.C. 
1361 et seq.) requires NMFS and the U.S. Fish and Wildlife Service 
(FWS) to prepare stock assessments for each stock of marine mammals 
occurring in waters under the jurisdiction of the United States, 
including the Exclusive Economic Zone. These reports must contain 
information regarding the distribution and abundance of the stock, 
population growth rates and trends, estimates of annual human-caused 
mortality and serious injury from all sources, descriptions of the 
fisheries with which the stock interacts, and the status of the stock. 
Initial reports were completed in 1995.
    The MMPA requires NMFS and FWS to review the SARs at least annually 
for strategic stocks and stocks for which significant new information 
is available, and at least once every three years for non-strategic 
stocks. The term ``strategic stock'' means a marine mammal stock: (A) 
For which the level of direct human-caused mortality exceeds the 
potential biological removal level; (B) which, based on the best 
available scientific information, is declining and is likely to be 
listed as a threatened species under the Endangered Species Act (ESA) 
within the foreseeable future; or (C) which is listed as a threatened 
species or endangered species under the ESA. NMFS and the FWS are 
required to revise a SAR if the status of the stock has changed or can 
be more accurately determined. NMFS, in conjunction with the Alaska, 
Atlantic, and Pacific independent Scientific Review Groups (SRGs), 
reviewed the status of marine mammal stocks as required and revised 
reports in the Alaska, Atlantic, and Pacific regions to incorporate new 
information.
    NMFS updated its serious injury designation and reporting process, 
which uses guidance from previous serious injury workshops, expert 
opinion, and analysis of historic injury cases to develop new criteria 
for distinguishing serious from non-serious injury. The NMFS Serious 
Injury Determination Policy was finalized in January 2012 and was first 
applied to the draft 2013 marine mammal SARs. The SARs report five-year 
averages for serious injury; thus, application of the new procedure 
involved retroactively reviewing the past five years of injury 
determinations for 2008-2012. NMFS defines serious injury as an 
``injury that is more likely than not to result in mortality'' (50 CFR 
229.2). Injury determinations for stock assessments revised in 2013 or 
later incorporate the new serious injury guidelines, based on the most 
recent five-year period for which data are available. NMFS solicits 
public comments on the draft 2013 SARs.
    On April 16, 2013, NMFS received a petition from the Hawaii 
Fishermen's Alliance for Conservation and Tradition, Inc., to classify 
the North Pacific humpback whale population as a distinct population 
segment (DPS) and delist the DPS under the Endangered Species Act 
(ESA). On February 26, 2014, the State of Alaska submitted a petition 
to delineate the Central North Pacific stock of the humpback whale as a 
DPS and remove the DPS from the List of Endangered and Threatened 
Species under the ESA. After reviewing the petitions, the literature 
cited in the petitions, and other literature and information available 
in our files, NMFS found that both petitioned actions may be warranted 
and issued positive 90-day findings (78 FR 53391, August 29, 2013; 79 
FR 36281, June 26, 2014). Currently, the four humpback whale stocks 
have depleted status under the MMPA due to their listing as endangered 
under the ESA. Consideration of both petitioned actions may affect 
their depleted status.

Alaska Reports

    In the Alaska region, SARs for 21 Alaska stocks (19 ``strategic'', 
2 ``non-strategic'') were updated. All stocks were reviewed and the 
following stocks were revised for 2014: Steller sea lion (western U.S. 
and eastern U.S. stocks), northern fur seal (eastern Pacific stock), 
spotted seal (Alaska stock), bearded seal (Alaska stock), ringed seal 
(Alaska stock), beluga whale (Beaufort Sea, eastern Chukchi Sea, 
eastern Bering Sea, Bristol Bay, and Cook Inlet stocks), killer whale 
(AT1 transient stock), harbor porpoise (Southeast Alaska, Gulf of 
Alaska, and Bering Sea stocks), sperm whale (North Pacific stock), 
humpback whale (Western North Pacific and central North Pacific 
stocks), fin whale (northeast Pacific stock), North Pacific right whale 
(eastern North Pacific stock), bowhead whale (western Arctic stock). 
Most revisions to the Alaska SARs included updates of abundance and/or 
mortality and serious injury estimates. Information on the remaining 
Alaska region stocks can be found in the final 2013 reports (Allen and 
Angliss, 2014).
    The Eastern stock of Steller sea lions was depleted under the MMPA 
due to its ESA listing as endangered. NMFS is currently evaluating the 
depleted status of the eastern Steller sea lion following delisting 
from the ESA. If not depleted, the recovery factor used to calculate 
potential biological removal level (PBR) would be adjusted from 0.75 to 
1.0 per the Guidelines for Assessing Marine Mammal Stocks, and PBR 
would be 2,193. If the stock continues to be classified as depleted, 
the recovery factor would remain at 0.75, and PBR would be 1,645.
    New survey data provided calculated values of abundance, minimum 
abundance (Nmin), and PBR for the spotted seal stock. Nmin is now 
reported as ``unknown'' and PBR as ``undetermined'' rather than a 
calculated estimate based on age of population estimate (>8 years old) 
for two stocks of beluga whales: Eastern Chukchi Sea and eastern Bering 
Sea.

Atlantic Reports

    In the Atlantic region (including the Atlantic coast, Gulf Coast, 
and U.S. territories in the Caribbean), reports for 53 stocks were 
updated and three added. Of the updated stocks, 9 stocks are 
``strategic,'' and 44 are ``non-strategic.'' Three new Atlantic region 
reports for strategic stocks were added this year, false killer whales 
(Western North Atlantic stock), common bottlenose dolphin (Central 
Georgia estuarine stock), and common bottlenose dolphin (Mississippi 
Sound, Lake Borgne, Bay Boudreau stock, previously contained in the 
common bottlenose dolphin, northern Gulf of Mexico bay, sound and 
estuary SAR). The Lemon Bay stock of common bottlenose dolphin was 
combined with the Gasparilla Sound, Charlotte Harbor, Pine Island Sound 
stock of common bottlenose dolphin, based on recent photo-ID data.
    All stocks were reviewed and the following stocks were revised for 
2014: North Atlantic right whale; humpback whale, Gulf of Maine; fin 
whale, Western North Atlantic (WNA); sei whale; sperm whale, WNA; North 
Atlantic killer whale, WNA; common bottlenose dolphin, Gulf of Mexico 
northern coastal; common bottlenose dolphin, Gulf of Mexico western 
coastal; common bottlenose dolphin, Barataria Bay; minke whale, 
Canadian east coast; Northern bottlenose whale; Sowerby's beaked whale; 
Risso's dolphin, WNA; long-finned pilot whale; short-finned

pilot whale, WNA; Atlantic white-sided dolphin; short-beaked common 
dolphin; common bottlenose dolphin, Western North Atlantic/offshore ; 
harbor porpoise, Gulf of Maine/Bay of Fundy; harbor seal, WNA; gray 
seal, WNA; common bottlenose dolphin, Gulf of Mexico continental shelf; 
common bottlenose dolphin, Gulf of Mexico eastern coastal; common 
bottlenose dolphin, Gulf of Mexico Oceanic; common bottlenose dolphin, 
northern Gulf of Mexico bay, sound and estuary (27 stocks); pantropical 
spotted dolphin, Gulf of Mexico; and Risso's dolphin Gulf of Mexico. 
Information on the remaining Atlantic region stocks can be found in the 
final 2013 reports (Waring et al., 2014).
    Most revisions included updates of abundance and/or mortality and 
serious injury estimates. The status of one stock, Gulf of Maine/Bay of 
Fundy harbor porpoise, changed from strategic to non-strategic. New 
survey data provided calculated values of abundance, Nmin, and PBR for 
the following stocks of common bottlenose dolphin: Gulf of Mexico 
continental shelf, Gulf of Mexico eastern coastal stock, Gulf of Mexico 
northern coastal stock, Gulf of Mexico western coastal, Mississippi 
River Delta, and Mississippi Sound, Lake Borgne, Bay Boudreau.

Pacific Reports

    In the Pacific region (waters along the west coast of the United 
States, within waters surrounding the main and Northwest Hawaiian 
Islands, and within waters surrounding U.S. territories in the Western 
Pacific), SARs were revised for 10 stocks under NMFS jurisdiction (5 
``strategic'' and 5 ``non-strategic'' stocks) and one was added for the 
Western North Pacific gray whale (a ``strategic'' stock). All stocks 
were reviewed and the following stocks were revised for 2014: Hawaiian 
monk seal; southern Resident killer whale; false killer whale, Main 
Hawaiian Islands Insular; false killer whale, Hawaii Pelagic; sperm 
whale, California/Oregon/Washington; Western North Pacific gray whale; 
California sea lion; Harbor seal, California; Northern elephant seal, 
California; Eastern North Pacific gray whale; and false killer whale, 
Northwestern Hawaiian Islands. Information on the remaining Pacific 
region stocks can be found in the final 2013 reports (Carretta et al., 
2014).
    New estimates of abundance for the California/Oregon/Washington 
stock of sperm whales are based on a Bayesian trend analysis that 
utilizes previously collected line-transect data (Moore and Barlow, 
2014), resulting in a more stable time series of abundance estimates. 
Mortality and serious injury estimates of California/Oregon/Washington 
sperm whales in California drift gillnets are updated, based on pooling 
additional years of data (>5 years) to reduce bias and improve 
precision in mean annual bycatch estimates (Carretta and Moore, 2014). 
The combination of new abundance estimates and pooling of bycatch 
estimates over a longer time period for this stock of sperm whales 
results in mean annual bycatch estimates that no longer exceed PBR.
