PolarTREC-Teachers and Researchers Exploring and Collaborating (PolarTREC) has provided the opportunity for over 160 K-12 teachers and informal science educators from the USA to work directly with scientists in the Arctic and the Antarctic. As a Teacher Research Experience (TRE), PolarTREC has engaged teachers with a unique professional development opportunity to increase their teacher content knowledge and learn about the polar regions by partnering with academic polar scientists who are conducting scientific research in the field. Stimulated by the IPY 2007–2008, PolarTREC has sent teachers on field expeditions for over a decade, and during that time has witnessed teachers not only experiencing the polar regions and bringing that experience back into their classrooms but also seeing their students learn more about the polar regions and become more interested in polar science. It is this secondary effect that is truly inspiring. This article profiles the journey to the polar regions of four PolarTREC teachers through their own perspectives and how they translated that experience into educational outreach opportunities.

The viruses circulating among Antarctic wildlife remain largely unknown. In an effort to identify viruses associated with Weddell seals (Leptonychotes weddellii) inhabiting the Ross Sea, vaginal and nasal swabs, and faecal samples were collected between November 2014 and February 2015. In addition, a Weddell seal kidney and South Polar skua (Stercorarius maccormicki) faeces were opportunistically sampled. Using high throughput sequencing, we identified and recovered 152 anellovirus genomes that share 63–70% genome-wide identities with other pinniped anelloviruses. Genome-wide pairwise comparisons coupled with phylogenetic analysis revealed two novel anellovirus species, tentatively named torque teno Leptonychotes weddellii virus (TTLwV) -1 and -2. TTLwV-1 (n = 133, genomes encompassing 40 genotypes) is highly recombinant, whereas TTLwV-2 (n = 19, genomes encompassing three genotypes) is relatively less recombinant. This study documents ubiquitous TTLwVs among Weddell seals in Antarctica with frequent co-infection by multiple genotypes, however, the role these anelloviruses play in seal health remains unknown.
