Dive in to our Ocean Showcase

With the launch of our new Ocean Showcase, you can now tour the ocean from the comfort of your web browser using the Google Earth plugin.

Follow along as National Geographic explorer, Sylvia Earle, narrates a tour through highlights of the Explore the Ocean layer in Google Earth. You can pause the tour at any time to watch videos of the surrounding areas and marine animals, like the humpback whales below.


Take a ride with the Monterey Bay Aquarium Research Institute (MBARI), as their Western Flyer research ship works off the U.S. west coast. View the discoveries they've made, like the transparent-headed barreleye fish.


Visit some exciting shipwrecks like the World War II USS Truxton Destroyer, and see divers explore the shipwrecks with video from Eco-Nova's Shipwreck Central.


Take a narrated tour of some of the world's best dive sites with Wannadive.net and the best surf sites with Wannasurf.com.




In addition, you can see some of the highest resolution data available of the ocean with the Underwater Terrain tour. And finally, let NOAA's Great Lakes Environmental Research Laboratory, GLERL, take you on a tour of the Great Lakes with a special feature on Lake Superior.


Over the past year, many photographers, naturalists, government groups and non-profit partners have added photos and videos to the Explore the Ocean layer in Google Earth, providing a great introduction to lots of ocean features. Enthusiasts continue to add photos and ratings to Wannadive.net and Wannasurf.com, improving the Ocean Sports layers.

Anyone can be a desktop Cousteau. And we welcome more contributions. Go here to tell us about your ocean data.

To take the plunge, download any tour and open it in Google Earth, where you can explore many more exciting ocean photos and videos by checking the Ocean folder in the left-hand layers panel.

WWII historical imagery in Google Earth

Many of us have heard stories, read books and watched films which show the many impacts of WWII across the world. Today we're giving you another way to understand this period in time - by exploring a new set of historical aerial images, taken over European cities during World War II, via the historical imagery feature in Google Earth. They can now be compared directly to images from the present day.

The historical imagery feature gives people a unique perspective on the events of the past using today's latest mapping technology. We hope that this World War II imagery will enable all of us to understand our shared history in a new way and to learn more about the impact of the war on the development of our cities.

Images taken in 1943 show the effect of wartime bombing on more than 35 European towns and cities. Imagery for Warsaw, which was heavily destroyed at the time, is available from both years 1935 and 1945. They remind us all of the devastating impact of war on the people in those cities and also the remarkable way in which urban environments are reconstructed and regenerated over time.

You can explore the German city of Stuttgart, which was subject to over 50 air raids during the War.




Naples was the most bombed in Italian city in WWII and the impact of these attacks can be seen here:



The French city of Lyon was the center of France's resistance movement against the German occupation. See how it was damaged and rebuilt over the years:



Imagery from 1935 and 1945 for Warsaw in Poland is particularly compelling. The city was amongst those most badly damaged in the war and comparisons with today are striking.

Contrast can be seen for example by comparing the imagery of the Historic Centre of Warsaw, a UNESCO World Heritage site, described as an 'outstanding example of a near-total reconstruction of a span of history covering the 13th to the 20th century'. The Royal Castle was completely burned to the ground, for example, and subsequently reconstructed, between 1971-1988.



Read more about one Googler's impressions here.

To access all the imagery for yourself, and compare to the present day cityscape, click the clock icon in the top-level toolbar to activate a time-line in the Google Earth display. Move back in forth in time by dragging the time slider from left to right or by clicking the back/forwards arrows.

Spotlight on historical imagery: Warsaw in 1935, 1945 and today

When I think about Poland, I think about my grandma. Babcia fondly recalled the Polish-American community of her childhood in Yonkers, N.Y., she told stories of traveling to Poland with my uncle, she read out loud the letters she received from our family there, and during Christmas she led aunts, uncles, and cousins in sharing a wafer called opłatek, which prompted hugs and kisses around the table. These are all good memories.

Like many, I have often used Google Earth to explore the world around me. When it comes to Warsaw, Poland, imagery now available from 1935 and 1945 reveals an opportunity to better understand the history of a city destroyed and rebuilt.

I studied the global devastations of World War II in school and read books about history, but the atrocities that took place during the 1930s and '40s bore little resemblance to much of the country I saw when I first visited in 2005. Poland had recently joined the European Union and brimmed with an overarching energy and enthusiasm toward the future, amidst reminders of a history that could not be forgotten. During three weeks spent traveling from Wrocław to Zamość and many places in between, I found myself mired in the contrasts between present and past: mesmerized by the beauty of Kraków, speechless with sorrow at Auschwitz.

In Warsaw, I stayed with cousins, ate plate after plate of pierogi and naleśniki, and explored the parks, squares, markets, and side streets that wove throughout the city. The realities of what had taken place only decades prior struck me powerfully at the Warsaw Rising Museum, which commemorates the resistance of the Polish Home Army. I left horrified and humbled. Four years later, here at Google I met with a representative working on the multimedia efforts of the Museum of the History of Polish Jews, set to open in 2012 on the site of the former Warsaw Ghetto. More than anything, we spoke about the fundamental importance of memory and the power of technology for sharing with a community around the world.

The following images are from 1935, 1945, and the present day. Click to enlarge.


The largest ghetto in all of Europe, the Warsaw Ghetto was the site of the deportations and murders of hundreds of thousands of Jewish people between 1940 and 1943, as well as the location of the Warsaw Ghetto Uprising.


























Founded in 1816, the University of Warsaw is Poland's largest university and the academic centerpiece of the city. Between 1939 and 1944, the university lost a majority of its buildings and collections, and many of its students and professors lost their lives.
























As we view these aerial scenes in Google Earth using the historical imagery time slider, we see the history of Warsaw against a much different landscape today. I think of how many grandparents, like my babcia, have shared stories of their childhoods and families, including memories both good and bad. Images like these help unlock and preserve the past even as we look to the present and the future.

Wander the seafloor like never before

If you happen to be a bathymetry buff, we've got an update that you'll be excited about (and if you're not, I hope you will be one by the end of this post). Most of the underwater terrain currently featured in Google Earth comes from the low-resolution US Navy/NOAA/SIO global grid. They're able to predict what the seafloor looks like using an extrapolation of water surface heights to estimate undersea mountains and canyons, based on radar data collected by satellite (if you're curious about this process, you can read Smith and Sandwell's more detailed explanation here). For most of the sea, that's all that's available. But a small part of the ocean has higher-resolution data available, based on echosounding sonar from ships, and it's now available in Google Earth.

Several organizations have provided their ship-collected data for publication in Google Earth to improve our undersea maps. The Center for Coastal and Ocean Mapping - Joint Hydrographic Center, has shared large swaths of underwater depth data collected from their expeditions north of Pt. Barrow, Alaska into the Arctic. The Living Oceans Society has shared their surveys off of the west coast of British Columbia, Canada, so you can now zoom around the Oglala seamount:


The California State University at Monterey Bay has collected high-resolution underwater terrain data for the entire California coast out to three nautical miles. We've published their data north and south of San Francisco Bay down to Ano Nuevo, where you can see the underwater ridges that elephant seals must navigate.


You can now also explore large undersea areas newly published from the Monterey Bay Aquarium Research Institute (MBARI), including our highest resolution underwater depth data featured to date: 1-meter terrain collected by MBARI’s Autonomous Underwater mapping Vehicles in Monterey Bay Canyon (see screenshot below), which is an underwater canyon larger than the Grand Canyon nestled between Santa Cruz and Monterey, California. MBARI has also shared ship echosounding maps that they've collected on the Davidson seamount, the Rodriguez seamount off of Santa Barbara, and terrain along the Juan de Fuca Ridge, as well as data collected off of the Oregon coast, from Beaver basin to the Heceta bank.

The MBARI Autonomous Underwater Vehicle (AUV) being launched from the Research Vessel Zephyr and one underwater. The MBARI Mapping AUV is a torpedo-shaped vehicle equipped with four mapping sonars that operate simultaneously during a mission. The sonars are a swath multibeam sonar, two frequencies of sidescan sonars, and a sub-bottom profiler. The multibeam sonar produces high-resolution bathymetry (analogous to topography on land), the sidescan sonars produce imagery based on the intensity of the sound energy's reflections, and the subbottom profiler penetrates sediments on the seafloor, allowing the detection of sediment layers, faults, and depth to the basement rock. All components are rated to 6000 m depth. The vehicle is launched on programmed missions and runs on its own battery power until it returns to the ship, as programmed, for recovery. The mapping AUV was christened the D. Allan B. in honor of MBARI's long-time Board member Dr. D. Allan Bromley of Yale University, who passed away in 2004.

Download this new undersea tour and open it in Google Earth to explore for yourself. Remember that only 5% of the world’s oceans have been explored, so much remains to be discovered.
We continue to publish new data in Google Earth, so check back. We thank all of the ocean exploring groups who have shared their data and welcome new contributions.

Take your places and searches to go with Google Maps for mobile

(Cross-posted from the Official Google Mobile Blog)

If you often use both a computer and a mobile phone in your daily routine, it can seem like a hassle when they don't stay in sync. You might spend time on your computer looking for a great used bookstore, only to forget the name of the place when you are ready to get directions from your phone. Sure, you could print directions in advance, but we believe smartphones are "smart" because they save you time. That's why today we're making your phone a bit smarter with the introduction of personalized suggestions and synchronized starring in Google Maps for mobile on Android.

Personalized suggestions make it easy to find places you've previously searched for. For example, imagine you're on your computer and you come across the Place Page for Mario's Bohemian Cigar Store Cafe. After reading reviews, you decide to stop in for lunch. When you're ready to go and want to get directions, just open Google Maps on your phone, start typing "mar," and you'll quickly see a suggestion - saving you from re-typing a long query and making it easier and faster to be on your way.





In addition, starring is a great way to save places to access them later. So whether you're standing at Amoeba Music with your phone or making plans to go there on your computer, you can star it so it appears on the map next time you're on either device. When viewing place details, just press the star icon next to the place name; these starred places are automatically synchronized between desktop and mobile, and can be accessed from both the "More" menu on your phone and from the My Maps tab on your computer.





Starring and personalized suggestions both require you to be signed in with your Google account, and your Web History must be enabled in order to use personalized suggestions.With synchronized starring and personalized suggestions, we hope to make your life easier when taking places and searches between your computer and phone. Both features are available in Google Maps 3.4. On Nexus One phones, you'll get this version of Maps after you accept the over-the-air update that started today. For other Android devices, starring and personalized suggestions will soon be available by downloading Google Maps 3.4 from Android Market. Lastly, be sure to check out the newly added "night mode" in Navigation, which will automatically turn on for easier Navigation viewing at night.

Here on the Google Maps team we're as excited as everyone else that the final season of the TV series Lost starts today. Our users are excited as well, and they've created maps to track the adventures of the Oceanic 6 around the world:
Please don't share these with Charles Widmore, as we don't really want him to know where to find our heroes! We're still working on that map of the island's movements and will post it when we catch up.
