The Monterey Bay Aquarium (MBA) is a public aquarium located in Monterey, California, United States. The aquarium was founded in 1984 and is located on the site of a former sardine cannery on Cannery Row. It has an annual attendance of more than two million visitors. It holds thousands of plants and animals, representing more than 600 species on display. The aquarium benefits from a high circulation of fresh ocean water which is obtained through pipes which pump it in continuously from Monterey Bay.

The centerpiece of the Ocean's Edge Wing, is a 28-foot-high (8.5 m), 333,000-US-gallon (1,260,000 l; 277,000 imp gal) tank for viewing California coastal marine life. In this tank, the aquarium was the first in the world to grow live California Giant Kelp. Visitors are able to inspect the creatures of the kelp forest at several levels in the building. The largest tank in the aquarium is a 1,200,000-U.S.-gallon (4,500,000 l; 1,000,000 imp gal) tank in the Open Sea galleries (formerly the Outer Bay), which features one of the world's largest single-paned windows. It is one of the few aquariums to hold the ocean sunfish in captivity.

Sealife on exhibit includes stingrays, jellyfish, sea otters, and numerous other native marine species, which can be viewed above and below the waterline. The Monterey Bay Aquarium is one of very few in the world to exhibit both bluefin and yellowfin tuna. For displaying jellyfish, it uses a Kreisel tank, which creates a circular flow to support and suspend the jellies. The aquarium does not house mammals other than otters.

There had been a number of attempts to build an aquarium in the Monterey area dating back almost 100 years. In 1914 an aquarium was proposed to the city council by Frank Booth with a cost of $10,000. A bond issue was sponsored in an attempt to place an aquarium in the basement of the Pacific Grove Museum by Knut Hovden in 1925 and in 1944 an aquarium is suggested for Point Lobos State Reserve.[4]

The aquarium occupies land at the end of Cannery Row (once Ocean View Avenue) in Monterey, at the site of the Hovden Cannery, a sardine cannery that helped to define the character of Monterey from the time it was built in 1916 to the day when it was the last cannery on the Row to close in 1973, after sardine fishing collapsed. This building was dismantled in 1980, but beginning in 2002 the Monterey Bay Aquarium has blown the original Hovden Cannery steam whistle at noon each day to commemorate it.[5]

The aquarium's original building was designed by the architectural firm Big Sur, including the wave machines in the Kelp Forest and aviary. His daughter, marine biologist Julie Packard, is currently Executive Director of the aquarium.

The aquarium was built in honor of the work of Pacific Biological Laboratories) and home resides next to the present MBA site.[6] Ricketts, whose life was an inspiration for the eventual building of the aquarium, is famous as the "Doc" of John Steinbeck's Cannery Row and Sweet Thursday. The aquarium itself contains a display of Ricketts' items, including some of his personal library. The shop also sells a variety of Steinbeck books.

Basic design

Front entrance of the Aquarium

The basic design of the aquarium pumps 7,570 litres (2,000 US gal) of seawater from the giant Kelp which are not suitable for ordinary saltwater aquariums.

The acrylic plastic (the same plastic as Plexiglas and Lucite) that makes the various tank walls ranges from 7.6 to 33 centimetres (3.0 to 13.0 in) inches in thickness, enabling them to resist the pressure and high total force of the water behind them.

Kelp Forest exhibit

The 28-foot-tall (8.5 m) 333,000-US-gallon (1,260,000 l; 277,000 imp gal) Kelp Forest exhibit was designed as the centerpiece of the aquarium, and was the first exhibit in the world to include a living kelp forest.[7] In addition to the bay water provided to all tanks, a surge machine at the top of this exhibit provides the constant water motion that kelp requires. The top of the tank is open, and was situated to maximize its exposure to sunlight during the day, thus further mimicking the bay. Eighty species of seaweeds grow in this exhibit, some of which have also entered the aquarium through the water from the bay rather than being deliberately planted. The kelp in this exhibit grows about 4 inches (100 mm) per day, and requires divers to trim it once a week.[8][9]

Each of the main windows in this exhibit is 8 feet (2.4 m) wide, 16 feet (4.9 m) tall, and 7.5 inches (190 mm) thick.[9]

Open Sea galleries

The largest tank in the Open Sea exhibit. The aquarium is known for housing an ocean sunfish and various great white sharks in this tank.

In January 1996, the aquarium opened the Outer Bay wing to provide exhibits covering the open-water ecology of Monterey's Outer Bay. The main 1,200,000-U.S.-gallon (4,500,000 l; 1,000,000 imp gal) tank in this area is the largest in the aquarium, and features one of the world's largest single-pane windows. Crafted by a Japanese company, the acrylic window is actually five panes seamlessly glued together through a proprietary process.[1]

This area was extensively renovated starting in August 2010, and re-opened July 2, 2011 as the Open Sea galleries. Another exhibit created at this time includes a school of 3000 sardines (a fish that was once the foundation of Monterey's economy), swimming against the endless current of a toroidal tank. As part of the Open Sea renovation, the aquarium also added a puffin exhibit, juvenile sea turtle exhibit, and multimedia experiences highlighting microscopic plankton.

Great white sharks

First shark

Beginning in September 2004, the Outer Bay exhibit (now the Open Sea galleries) was the home to the first great white shark ever successfully kept on exhibit. The shark was at the aquarium for 198 days (the previous record was 16 days). The shark was released on March 31, 2005 after she bit two soupfin sharks in the exhibit, both of which later died. The aquarium staff believe the shark may have been acting to defend territory, as she did not eat the soupfin sharks.

Second shark

On the evening of August 31, 2006 the aquarium introduced another great white shark to the Outer Bay exhibit. The juvenile male was caught outside Santa Monica Bay on August 17[10] and was released on January 16, 2007. The shark had grown from an initial length of 5-foot-8 and 103 pounds when it arrived on August 31, 2006 to 6-foot-5 and 171 pounds on release. Data from this second white shark was transmitted back to aquarium staff from a pop-off satellite tag after 90 days.

Third shark

For the third time since 2004, the aquarium had a young great white shark in the Outer Bay exhibit in 2007/2008. He arrived on August 28, 2007 and was released on February 5, 2008. Like the first shark in 2004, he was caught accidentally in commercial fishing gear. Like the second shark in 2006, he was a young male: just 4-feet, 9-inches long and weighing 67 ½ pounds. As with the previous great white sharks, he was kept in an ocean holding pen off Malibu in Southern California until he could be observed feeding and navigating well in the confines of the pen.

Fourth and fifth sharks

A fourth great white shark, a young female, was kept in August/September 2008; the fast release being due to its unwillingness to feed.[11]

From late August 2009, the young female was again featured in the Outer Bay exhibit and reportedly did well.[12] She was successfully released to the wild in early November 2009, but died after being caught in early March in a gillnet set by a fisherman in waters off Ensenada, Mexico.[11]

Sixth shark

The sixth individual was caught off of Malibu on August 18, 2011, and was placed in the Open Sea exhibit on August 31, 2011. It was released on November 1, 2011 off Point Conception and was reported dead soon after.

Other exhibits


Magellanic penguins being fed and their individual consumption recorded for health monitoring purposes

In March 2000, the aquarium opened a penguin exhibit as part of its Splash Zone family galleries, to complement the already popular sea otter exhibit. Formerly, two penguin exhibits housed Magellanic penguins from South America and African Black-Footed Penguins. Today, the Black-Footed Penguin exhibit is the only penguin exhibit at the Monterey Bay Aquarium, with 18 individuals (nine breeding pairs) residing in the second floor enclosure. The aquarium also hosted 19 penguins from the Aquarium of the Americas in New Orleans along with two sea otters after that aquarium was badly damaged by Hurricane Katrina.

Jellyfish Special Exhibit

On March 30, 2012, the aquarium opened "The Jellies Experience," a $3.5 million special exhibition that takes visitors into the world of jellies in a blend of live exhibits and interactive experiences. It includes species never before exhibited at the aquarium, including elegant jellies, as well as favorites like comb jellies, flower hat jellies and blubber jellies. The exhibit offers psychedelic-themed interactive experiences: Visitors can, with a wave of their arm, spark fluorescent displays of jellies and corals; create a digital jellyfish and launch it into a virtual ocean with creations made by other visitors; prompt digital jellies to “dance” with them; and become part of a kaleidoscopic image.

The Monterey Bay Aquarium has been the first in the world to exhibit jellyfish, which were traditionally impossible to cultivate. Marine biologist and ecologist[13] Dr. Wulf Greve had come up with the concept of the "Planktonkreisel"[14] for his own research on Pleurobrachia Pileus in 1968 at the Biologische Anstalt Helgoland. Building on this work, the Monterey Bay Aquarium was the first to ever add jellyfish to their exhibit in the early 90s.[15]

Tentacles Special Exhibit

In spring 2014, the aquarium opened "Tentacles: The Astounding Lives of Octopuses, Squid and Cuttlefishes." Over the life of the exhibit, visitors to Tentacles might see any of the two dozen species that will rotate through a dozen living exhibits, from giant Pacific octopus to Hawaiian bobtail squid, the Wunderpus and others – including one of the world’s smallest squid and one of the world’s largest cuttlefishes. From time to time there may also be displays of never-before-exhibited deep sea squid and octopuses collected in collaboration with the aquarium’s sister organization, the Monterey Bay Aquarium Research Institute. Tentacles includes multimedia interactive exhibits that dramatize the features that set these animals apart, and art pieces highlighting 4,000 years of human fascination: replicas of Minoan pottery and tiles from Pompeii and Herculaneum; Victorian-era scientific and literary illustrations; modern-day tentacle tattoos; and contemporary mechanical sculptures commissioned exclusively for the exhibition.

Marine research

Monterey Bay Aquarium staff conducts field research on great white sharks, sea otters and Pacific tuna to better understand these species – their migration patterns, population dynamics, food requirements and the threats they face in the wild. Years of data has led to insight into the lives of these animals. Aquarium staff are also involved in research on sevengill sharks, cookie cutter sharks and mobulid rays, as well as ocean sunfish and Humboldt squid, in addition to propagation efforts on several species jellies, seahorses and tropical corals. The aquarium is also one of the main rehabilitation sites for shorebirds in Monterey County, including the western snowy plover. Since the plover recovery program began at the aquarium in 2000, aviculturists have banded and released 58 snowy plovers of all ages.

The Monterey Bay Aquarium maintains a close relationship with the Monterey Bay National Marine Sanctuary (MBNMS) a federally protected marine area (the equivalent of a saltwater national park) off California's central coast. The aquarium is also home to Seafood Watch, which publishes consumer guides for sustainable seafood purchasing.

Funding and staffing

The Monterey Bay Aquarium was endowed initially with a personal gift from David and Lucile Packard, with the vision that the aquarium would be self-supporting after it opened. Initial construction cost was US$55 million. The David and Lucile Packard Foundation, other foundations and individuals support some programs of the aquarium. Operating costs are largely covered by visitor admission, as well as by special events and membership dues.[17] No government money is involved, with the exception of an occasional federal grant given to visiting scientists, for study. The aquarium is organized into three institutions: Monterey Bay Aquarium Foundation, the Support Services, which manages some aquarium-owned property, and the independent Research Institute, which operates three ocean-going research vessels.

The MBA has about 420 employees and 1270 volunteers.
