Contribute Photos

Browse photos that others have contributed to this growing database.

You can contribute to the repeat photography database in several ways.

First, you can take one or more repeat shots of photographs we currently have in the database using our guidelines.

Second, you can establish new photo sites, such as looking out from a public use cabin or a kayak launch beach. Keep in mind that these photos are used to track changes in the landscape over time. Also, frame your photo with an easy to notice reference point for others who may repeat it in the future.

Contribute photos via Flickr

Suni

Uploading photos to Flickr and attaching them to the SWAN repeat photography database is simple. Here are the steps to follow.


  • First, set up an account with Flickr or log in using an existing Yahoo, Google, or Facebook account.
  • Information on how to do this is provided via Flickr
  • Second, join one or more of the groups associated with the Southwest Alaska Repeat Photography database.


  • Next, upload your photos. Be sure to add them to the appropriate group as you upload. Also, include additional information with the photo, such as the GPS coordinates, location name, etc.
  • Finally, view your photos on our embedded slide shows.

Historical photographs combined with archived data supplement other sampling methods and help us understand change over time. Repeat photography also helps interpret the data collected by other means..

Weather and Climate

Climate refers to the long-term patterns in weather of a given area. Today, scientists record temperature, precipitation, snow depth, and other short-term parameters to track long-term patterns.Since installing the weather stations, we've learned that the temperature routinely reaches 70F on the Harding Icefield during summer months. Winds of over 100 miles per hour have been recorded by several stations during winter storms. Maintaining the stations is an ongoing effort and involves annual visits to each remote location.

Glaciers

In many cases, photos are the first records of a glacier's physical characteristics and provide valuable information about the terminus, or face, of the glacier as well as its height and area of coverage.

Ninety percent of the glaciers in Alaska are retreating, including Holgate, Cape Douglas, Mount Mageik, and Kenibuna Lake glaciers.

Plant Communities

Since installing the weather stations, we've learned that the temperature routinely reaches 70F on the Harding Icefield during summer months. Winds of over 100 miles per hour have been recorded by several stations during winter storms. Maintaining the stations is an ongoing effort and involves annual visits to each remote location.

Seasonal Processes

Seasonal events, such as the green up of forests in spring or the onset of lake ice in winter, are cues for many other natural processes like migration and mating. In addition, they can help scientists determine long-term trends in seasons and the effects of climate change.

SWAN is using satellite imagery and phenocams to visually monitor seasonal processes.

Landscape Changes

Large, landscape-level changes in vegetation types serve as both a driver of and response to changes in the environment. Repeat aerial photography is the primary tool used by scientists to categorize landscapes (ie. figure out which areas are forests and which ones are meadows) and to track changes in the national parks of southwest Alaska. When combined with photography and species observation on the ground, the aerial images form a detailed record of the changing landscape. While some changes in landscapes are correlated with climate change, others are due to fire, volcanic eruptions or earthquakes.

See evidence of volcanic activity at Half Cone.

Coastal Change

Coastlines in southwest Alaska are dynamic and constantly changing. Changes to coastlines are often caused by storm-driven waves, hide tides, currents, runoff, landslides, and earthquakes. These changes alter the vegetation, animal communities and shore-type and have implications for humans and land management. Scientists with the National Park Service are monitoring coastal change using repeat aerial photography and satellite imagery. The photographs are then compared to surveys conducted along the shore to determine change.

See examples of coastal change at Aniakchak Bay, Seal Split, and Cape Douglas.
