Produkten visar strandlinjens läge längs Sydsveriges kust som den tolkats från ortofoton från olika år. Som underlag har använts Lantmäteriets rektifierade historiska ortofoton samt ortofoton från 1939–1940 från Geocentrum, Lunds universitet. De flesta av Lantmäteriets ortofoton är sammansatta av en mosaik av bilder från olika årtal. I de fallen har en uppdelning efter årtal gjorts och bilderna har grupperats i decennier avseende flygår. Bilderna finns från 1970-talet, 1960-talet, 1950-talet och 1939-40 och täcker in större delen av den skånska kusten. Produkten innehåller också en analys av hur strandlinjen förändrats från 1940 till 2010.

I många sjökort finns specialer, d.v.s. oftast mindre områden som redovisas i bättre skala än huvudkortet. Mestadels över större och mindre hamnar.

Maringeologi 1:25 000 innehåller uppgifter om jordarternas och bergets utbredning inom svenskt territorialhav och svensk ekonomisk zon (EEZ). Produkten ger bland annat information om bottenmaterial, olika sediments mäktighet och bildningssätt samt innehåll av organiskt material. SGU ansvarar för att utforska och kartlägga bottenförhållanden inom svenskt territorialhav och svensk ekonomisk zon (EEZ). Informationen som tas fram används som underlag vid planering av och beslut om skydd och nyttjande av havsbottnen, bland annat vid projektering av marina anläggningsarbeten och vid miljöövervakning. Den utgör också viktigt underlag vid biologiska inventeringar samt för Försvarsmakten.

Korten täcker hela Sveriges skärgård. De används vid navigering inomskärs och i kustnära områden. Skalan är vanligtvis 1:50 000.

MSB har tagit fram 9 st utbredningsskikt längs hela Sveriges kust för en vattenståndsnivå från 1 m till 5 m i RH2000. En förenkling har gjorts för att underlätta hanteringen av de stora datamängderna. Det innebär att öar mindre än 5000 kvadratmeter som riskeras att översvämmas har tagits bort och illustreras därför som översvämmade vid respektive havsvattenstånd.

The Coastal Infrastructure Vulnerability Index (CIVI) was jointly developed by DFO Science Branch, Small Craft Harbours (SCH) Program and the Economic Analysis and Statistics Directorate. The CIVI was designed with the intent of developing a climate change adaptation tool that would support management decisions regarding the long-term infrastructure planning for SCH sites. The CIVI provides a numerical indication of the relative vulnerability of small craft harbour sites to the effects of climate change and was designed with three component sub-indices: Environmental Exposure (natural forces), Infrastructure, and Socio-economic. The spatial component for the coastline was derived from the CanVec 1:50,000 hydrographic layer (https://open.canada.ca/data/en/dataset/9d96e8c9-22fe-4ad2-b5e8-94a6991b744b). This layer combines the 1:50,000 CanVec coastline of Canada with the following CIVI environmental exposure variables: - projected sea level rise (for the decades 2030, 2040,...2100) in meters - wave height (metres) and wind speed (metres/second) - change in sea ice coverage in Atlantic Canada from the 1970s to the 2000s Sea level change: Data for relative sea level change (SLC) were derived from the Intergovernmental Panel on Climate Change Fifth Assessment Report (IPCC 2014, AR5). The projected relative sea level change under the high emission scenario (RCP8.5) was calculated for all years between 2006 and 2100. Sea level change for the years 2030, 2040, 2050, 2060, 2070, 2080, 2090, and 2100 were used. Wind Speed and Wave Height Modelled hindcasts of yearly maximum wind speed (1990 - 2012) and wave height (1990- 2014) were used. This dataset was generated from IFREMER wave hindcasts using the WAVEWATCH III model with wind data from NCEP Climate Forecast System Reanalysis (CFSR) (Saha et al. 2010). Two high resolution (10 minute) grids of Atlantic and Pacific maximum modeled wind speeds and maximum significant wave height were used for southern Canadian coastal areas while a coarser (30 minute) worldwide grid was used for the Arctic areas. From these datasets the mean annual maximum wind speed over 23 years and the mean maximum significant wave height over 25 years were calculated. Change in sea ice coverage: Sea ice data from the Canadian Ice Service were acquired for Atlantic and Arctic Canada, representing percent ice coverage for each week over four decades (1970s, 1980s, 1990, 2000s). For each decade a single dataset was calculated to represent the sum of all weeks with ice coverage in excess of 50%, with a maximum possible score of 52 weeks for each decade. To measure change in ice duration, the summary mapsheet from the 2000s was subtracted from the 1970s summary mapsheet. The final dataset represents the change between the 1970s and 2000s in the number of weeks with ice concentrations greater than 50%. A positive number indicates a reduction in weeks of ice coverage, a negative number an increase in ice coverage. The data for individual small craft harbours included here contains predicted sea level change for the decades between 2030 and 2100, wave height, windspeed, change in sea ice coverage, population, and the final environmental exposure sub-index value (ESI). The population for each harbour is derived from the 2016 Census of Canada data for the Census subdivision (CSD) geographic unit.

Bay Scale Assessment of Nearshore Habitat Bras d'Or Lake - Chapel Island 2008 data is part of the publication Bay Scale Assessment of Nearshore Habitat Bras d'Or Lakes. A history of nearshore benthic surveys of Bras d’Or Lake from 2005 – 2011 is presented. Early work utilized drop camera and fixed mount sidescan. The next phase was one of towfish development, where camera and sidescan were placed on one platform with transponder-based positioning. From 2009 to 2011 the new towfish was used to ground truth an echosounder. The surveys were performed primarily in the northern half of the lake; from 10 m depth right into the shallows at less than 1 m. Different shorelines could be distinguished from others based upon the relative proportions of substrate types and macrophyte canopy. The vast majority of macrophytes occurred within the first 3 m of depth. This zone was dominated by a thin but consistent cover of eelgrass (Zostera marina L.) on almost all shores with a current or wave regime conducive to the growth of this plant. However, the eelgrass beds were frequently in poor shape and the negative impacts of commonly occurring water column turbidity, siltation, or possible localized eutrophication, are suspected. All survey data were placed into a Geographic Information System, and this document is a guide to that package. The Geographic Information System could be used to answer management questions such as the placement and character of habitat compensation projects, the selection of nearshore protected areas or as a baseline to determine long term changes.
