The Mediterranean and desert regions of Southern California include some of the most diverse bee faunas (Hymenoptera: Anthophila) in the world. Due to human development, large portions of Mediterranean scrub and desert ecosystems in Southern California have been destroyed or profoundly degraded. This trend of habitat destruction and degradation is expected to continue as population pressures continue to grow and as Earth’s climate changes. This ongoing inventory project seeks to document all the bee species that occur within the bounds of San Diego County. Our aim is to not only make this information available for conservation managers and scientists, but ...

Collection of printed and manuscript materials created between 1965 and 1998 by 23 distinct revolutionary groups in Mexico. The collection is particularly strong in ephemeral communiques and revolutionary periodicals such as "13 de junio," "Madera" and "Militante." Images were digitized from originals held by the UC San Diego Library.

This collection includes separate data sets of atmospheric aerosol submicron particle composition that include organic functional group concentrations at locations within the Arctic. Measurements include analysis of ambient aerosol particles sampled on Teflon filters that were analyzed by Fourier transform infrared (FTIR, Bruker Tensor 27) spectroscopy in a temperature and humidity controlled clean room. The FTIR spectrum for each filter was analyzed with an automated algorithm that baselined the spectra. Absorptivity and molar masses were used to convert peak area at specific wavenumbers to mass for the organic functional groups: hydroxyl, alkane, amine, carboxylic acid, and carbonyl. The total organic ...

This collection contains the lifecycles of global atmospheric river (AR) objects. This data was produced by isolating regions of enhanced IVT transport events by applying the Atmospheric River-CONNected objECT (AR-CONNECT) algorithm. AR-CONNECT is a four-dimensional (4D) object-oriented algorithm, adapted from the CONNECT algorithm developed by a team of researchers from the University of California, Irvine [Sellars et al., 2013, 2015, 2017]. The algorithm uses a seeded region growing segmentation technique to segment AR lifecycles according to their high-intensity cores. AR-CONNECT determines the lifecycles of an AR by using a flood-filling algorithm to group discrete AR timeslices where they are contiguous ...

This collection contains raw data from a REMUS-100 autonomous underwater vehicle (AUV) deployed over the Makua reef shelf, Oahu, Hawaii on 6-8 September 2013. The dataset includes the vehicle’s location (latitude, longitude), orientation (yaw, pitch, roll), and time (UTC) as well as pressure and velocity measurements from upward- and downward-looking 1200 kHz RDI Doppler velocity logs (DVLs) onboard. Velocity data were collected in ship coordinates. Hydrodynamic surveys consisted of mow patterns with repeated transects in both the cross-and alongshore directions in water depths ranging from 5 to 30 m. The surveys spanned an alongshore distance of about 1600 m, with ...

A collection of over 1,400 postcards primarily depicting Southern California, Baja California, and the American Southwest. Major themes include San Diego's areas of interest, the US-Mexico border region, Tijuana, Ensenada, Mexicali, Tecate, the California missions, and the US Navy. Popular tourist destinations such as the Hotel del Coronado, Balboa Park, and La Jolla Cove are particularly well-represented, as are postcards featuring the 1915 Panama-Pacific International Exposition and the 1939 Golden Gate International Exposition in San Francisco. The collection was scanned in its entirety and may be searched by date, geographical region, publisher, subject matter, and key words from captions and ...

Bear Facts was the newsletter published by the Oceanids, a service and social organization promoting friendship and services to the UC San Diego community. Oceanids began as a women’s organization in the Scripps Institution of Oceanography and remains active today. The newsletter is currently known as Oceanids News and is available through the organization’s website.

The Ben Yellen Papers document grassroots social and political activism on the subjects of farm labor, commercial agriculture, and western water policy in Southern California. In 1942, Ben Yellen (1907-1994) settled in the town of Brawley in Imperial County, California, the center of one of the richest and most productive agricultural regions in the United States. In the late 1950s, Yellen initiated a protracted battle against the large-scale growers who dominated the region's economy and their representative institutions, including the Desert Growers Association and, especially, the Imperial Irrigation District (IID). The digitized portion of the collection focuses on Yellen's self-published ...
